    Some of you that have followed me for a while might recognize this project as an upgraded version of my water bottle rocket launcher, seen in this video: • Turn Empty Water Bottl...
    While the old design was the cause of quite a few singed arm hairs, this new model is much more pleasant to use due to the new blast shield as well as the distance from the rockets that has been achieved by having the igniter on a longer leash. Even so, safety glasses are a required precaution, just in case.
    I recently participated in leading some science based activities for grade school aged kids and these bottle launchers were a big hit. The kids had a lot of fun attaching craft foam fins onto the bottles with duct tape and hot glue. The launchers themselves only take about 20 minutes to put together, so it's a quick and easy project that offers a ton of entertainment.
    The rockets are fueled by the combustion of rubbing alcohol, which is ignited by the spark from a barbecue igniter. I used rubbing alcohol with a concentration of about 90% in the video, but any concentration of 70% or greater should work just as well. When fueling the bottles, the most important step as shown in the video is to whip the last drops of liquid alcohol out the open end. This brings the fuel/air mixture to the proper level for a good combustion, and reduces the liquid alcohol particles expelled from the rocket upon launch that otherwise could melt the plastic blast shield or cause minor burns.
    A neat trick I did not mention in the video is that once the bottles have been fueled, rather than pushing them onto the launcher the cap can be put back on the bottle to have it ready to fire later.

    For those who didn't manage to get the ignition. If you have >70% alcohol and you're sure you have the spark, it has to be the temperature of the mixture. I was having problems with ignition when the temperature was below 20 Celsius. What you can do is you can use a hairdryer to warm the bottle. Then it works every time. Good luck!
    Btw.@NightHawkInLight awesome idea!

    • @keebearfull
      @keebearfull 9 ปีที่แล้ว +3

      Good and workable idea. Temp is critical. However, remember that the as the hand held hair dryer runs it has continuous sparking inside the electric motor. The alcohol vapor can waft to the mouth of the plastic bottle. If too near the spark, it can ignite and you'll be holding a flame thrower bottle. In a similar experiment - to my surprise - I had an alcohol vapor flame shooting off the bottle. (I was sure the vapor was not close/concentrated enough - I was wrong.) The result was exciting but quite unsettling.

    I tried this experiment and it worked great! What I also found is that after swinging the fuel drops out you should give it a quick blow into the mouth of the bottle. I compared that launch to ones where I didn't blow into it and the one where I blew into it flew significantly farther. I recommend giving it a quick blow before each launch. I found out that if you leave even small amounts of alcohol in the bottle, it will sometimes drip onto the launcher and set it on fire after launch. But anyways, Thank you for the amazing project! The kids in the neighborhood love it!

    Mine didn't go very far like in the video. It was a little disappointing. But then I changed bottles and it was really cool! The first bottle was wide at the top (Pepsi bottle), whereas the other was more narrow and fit more snuggly on the pipe (Sprite bottle). It makes quite a bit of difference.

    Thanks for this video. A few notes: You can get 99% rubbing alcohol now which might work better for sparking if you are having any issues.
    Most grill igniters will NOT WORK since they only have 1 probe. They assume you set up that probe right next to a metal gas port to make the spark. As such, you need to have a TWO CHANNEL one, and use one wire from each.
    I used the 3 channel brinkmann igniter, capped the third one, and used the wires from channels 1 and 2 to spark to each other. They even have nice terminators at the end. You discard the probe thingees themselves.
    I also recommend NOT using a piezoelectric since you have to push really hard on the button to make the internal hammer hit the quartz crystal. A 1xAA is much nicer, on a relatively flimsy launcher.

    I made these and tried using a couple different fuels: 95% Isopropyl Rubbing Alcohol, Denaturated Alcohol, Ethanol, Methanol, Gasoline, and Nitro RC Fuel and the Nitro RC Fuel and Ethanol seem to be the most powerful and easiest to use. When using gasoline, you need to use a very small amount of gasoline and you need to blow into the bottle a lot in order to achieve an air-fuel ratio that will burn because if you don't, the mixture will be too rich to ignite. Gasoline also produces a very bright flame compared to the others, and also produces black smoke and soot inside the bottle. Next I might try oxyacetylene!

    What you have here used to be referred to as a spigot mortar, because the "barrel" is INSIDE the projectile rather than ENCLOSING it
    During WW Two, they were used in anti-submarine warfare. They were better than depth charges, as they wouldn't go off unless they hit something.
    A ship would be fitted with racks of up to 20 mortars, slightly splayed out so that, when fired, the bombs would form a spread out pattern, making it more likely they'd hit a submerged sub

    About 50 years ago we made tennis ball canons out of pop cans. Of course the cans were way different back then in design and these ones had the zip tope or shall I say pull tab tops. 4 or 5 cans cleanly cut then a rough cut and to trap the ball and then on the other end of that a untouched top with the pull tab whole and a two can chamber. Add a small hole in the center of the bottom four ignition and fuel addition. My first one was taped together with a number of layers of electrical tape and was fueled by gasoline. Squirt a little gasoline in the butt end and then start shaking the apparatus around to get some air into it. Drop a tennis ball in the top and it slid down very nicely until it hit the jagged part. Lighte it off and boom that puppy would send tennis balls a hundred yards. I improved on it by using much much better tape plus a whole heck of a lot more including covering the whole surface and then used a spray can of starting fluid a.k.a. ether for the fuel. You could either shoot a tennis ball or just make one super loud boom. Kind of like the old carbide canons. I had a lot of fun with it in college.

    This was for my daughters science project. If you are getting a good spark, I believe it is most likely is a fuel problem. Like others, we were using 91% alcohol from the grocery store. After trying for half an hour we only got it to fire 2 times in 70F degree weather. The spark also had all but disappeared after half an hour trying. I tried burning the 91% alcohol in an alcohol stove and it would not light, I think it may be watered down. I let it dry out (30 min), the spark was better, so we made sure we had a good spark across about an 1/8 inch (3mm) gap. We switched to Everclear 95% grain alcohol, which is what I use in my alcohol stove. The rocket fired in 1-3 clicks every time.

    Made this fun project. Some things I learned.
    I found that "not less than 99%" alcohol gave me 100% function.
    The igniter has more than enough spark.
    I made one with a kind of stun gun igniter, and it didn't help with any lower content alcohol.
    Need to be sure NO liquid alcohol is in the bottle. I almost burnt one up when the liquid kept on burning in the launcher.
    Found out, by mistake, it sometimes fires twice, after first firing, without adding more alcohol.
    Stuck the bottle on after firing, and wanted to check for spark. BANG!!! it went off.
    Always point it in a safe direction, and don't do it indoors.
    Because it's so loud, I only fire it at the shooting range.
    Has anyone fired it at night????
    Is there any flame????

    One curious thing I had happen-I launched a bottle horizontally across the yard as a test, with a chain link fence as backstop. When I picked up the bottle, it had a ton of dirt in it! I think this is because the gases cooled and contracted around the same time the bottle bounced off the ground, so it sucked in dirt. This makes me wonder if it also pulls in enough oxygen again for the next launch.

It is ~ 40-45 deg out so I moved from rubbing alcohol to hairspray but I still cannot get the rocket to launch consistently. It seems like my spark is very dim once I put the bottle on the launcher.

      +Donny Bui Hey sorry for the delay in my reply, I don't know how I didn't see this comment earlier. It could be that your alcohol is a bit too cold. Try keeping it indoors before taking it out to fire the rockets. The higher the concentration of alcohol the better. 91% is the most common and works well. The dim spark may be from overfueling, which would mean you need to give the bottles an extra shake or two before putting them on the launcher so they get more fresh air mixed with the alcohol.

    • @Nighthawkinlight
      @Nighthawkinlight  9 ปีที่แล้ว +1

      If you're getting spark but the rocket is not firing it means your fuel to air ratio is incorrect for proper combustion. If you have too much fuel vapor in the bottle the spark will be a bright neon blue. If so, take the bottle off and shake it a few more times as if you were swinging out extra liquid, that will mix more air in and get rid of excess fuel. If the spark looks the same color as it is when the bottle is off you probably don't have enough fuel and you should shake the liquid alcohol around more before draining it.

    • @glennkachmarscienceguy
      @glennkachmarscienceguy 9 ปีที่แล้ว

      NightHawkInLight This is what someone on Reddit (maybe you) told me yesterday. So today I spent a lot more time shaking it out and introducing oxygen various ways. Nothing worked. Also because I am not that knowledgeable about piezoelectricity, does it matter that the wire that the spark jumps to is not attached to anything? Because I had a spark I assumed it wouldn't matter, but at this point I am considering all options. Thanks for the response (and so fast too).

    • @Nighthawkinlight
      @Nighthawkinlight  9 ปีที่แล้ว +1

      Glenn Kachmar Yes that was me that replied on Reddit. The wire that the spark is jumping to should be attached to the second terminal on the igniter. In any case, between tests are you letting the bottles air out all the old fuel? If you just keep adding more while there's already some in there it will be over fueled for sure. If you take a match to the back of a bottle that you have failed to fire does it ignite the fuel inside and burn with a 'woosh'? If not then it's not properly fueled. If it does ignite and burn very quickly it is properly fueled and you can then know that it's your spark gap that needs adjustment, not the fuel. Wear cotton gloves to protect you if you try this, not synthetic, because synthetic gloves will melt to your skin if they catch fire.

      NightHawkInLight Now that I think about it, another reason I didn't attach it was that there seemed to be anywhere to attach it to. A guy in a BBQ dept. gave me the igniter and it just had a stub like end next to a thick wire with ceramic insulation cylinder around part of it. It didn't seem to be a circuit and it made a spark so I thought I don't need to make it a circuit. It was mostly guesswork as you can imagine. Sorry to keep peppering you with questions, but will I get a stronger spark if I remake it making sure that it is a circuit?

    • @Nighthawkinlight
      @Nighthawkinlight  2 ปีที่แล้ว

      Yes, various alcohols will work fine if 90+% concentration. You may want to look at my newer propane bottle rocket launchers as they are more reliable in cold weather where alcohol does not evaporate so easily.

    When I was a kid, we used to make tennis ball canons. They were tin beer and coke cans, 3 with the bottoms and tops cut off and one at the bottom with top and bottom still on it, all taped together. The bottom can had a small hole about an inch from the bottom. The hard part was carburating the lighter fluid and air just right. Kids assume that the more lighter fluid, the bigger the boom. That's not the case. And I figured out by accident the best way to carburate it. Just a squirt down the top, then one good swing holding the bottom with the top outwards, them shoving the tennis ball in right after swinging it. Light it at the bottom hole. DO NOT USE GASOLINE. USE ZIPPO LIGHTER FLUID ONLY. DO NOT POINT IT AT ANYONE.

    This could probably be done a lot more simply. Just tape a pushbutton-igniting propane torch to one end of a 1/2" pipe, put the neck of the 2l bottle on the other end as shown, wiggle the smaller bottle on the other end also as shown, then flow mixed air/propane into the bottle from the torch for several seconds and pull the trigger. A way to vent air from the bottle as propane/air mix flows in may or may not be necessary.

    Wouldn't it make more sense to ignite the mixture near the opening? Because I'm sure a lot of unburned fuel gets pushed out of the bottle before it ignites. You could make a comparison

    • @Nighthawkinlight
      @Nighthawkinlight  9 ปีที่แล้ว +7

      In the rocket aspect, yes. But the pipe extending deep into the bottle actually makes it fire off more like a cannon in the first instant of ignition, which gives a huge extra boost in initial speed.

  • @jacobmacdavid6803
    @jacobmacdavid6803 6 ปีที่แล้ว

    Successful ignition is temperature dependent. I made this launcher on a cool (65 degrees F), overcast day, and had no success. I tried it again on a warmer (75 degrees F) sunny day, and it ignited every time. It didn't at first, but I left the alcohol (70%) and the bottle out in the sun for about 30 minutes, and then it worked perfectly.

    Thank you for sharing! I made a handheld version of this using just 1/2 inch PVC pipe, an elbow, and a couple PVC caps. I'm still having trouble getting this to fire, but I wonder if it's because of the bottles I'm using. I was trying small drinking bottles, but found out that the bottles were not airtight, so I'm wondering if the vapor is possibly leaking out. I'll try using 2 liter bottles as demonstrated in the video, and I'll let you know how it goes. Thanks!

    • @Nighthawkinlight
      @Nighthawkinlight  9 ปีที่แล้ว

      I'm not using 2 liter bottles, they're 12oz. Still small. If you're having trouble firing it's almost certainly because you're using too much or too little fuel.

    • @CollinSexton
      @CollinSexton 9 ปีที่แล้ว

      NightHawkInLight I've tried a couple of different sizes now, and still can't seem to get it to fire. I tried using a lighter, and was surprised with how much thrust shot out at my hand. I'll try different things, though, and hopefully I'll get it to work.

    • @Nighthawkinlight
      @Nighthawkinlight  9 ปีที่แล้ว

      ***** It may be your spark gap that needs adjustment in that case.

    • @CollinSexton
      @CollinSexton 9 ปีที่แล้ว

      NightHawkInLight That's what I was thinking. I think I'm using too much wire, because the spark seems fairly week, but still looks the same as the one in the video. I'll try to fix the spark gap and lose a little bit of wire, and hopefully that'll help.

    • @CollinSexton
      @CollinSexton 9 ปีที่แล้ว

      NightHawkInLight Alright, so I still can't get this to fire. I've messed with the spark gap and fuel ratio, and tried different bottles as well. I even tried hairspray (which was mentioned in the comments, NOT a safe idea by the way). I tried it with hairspray while the bottle was on the tube, and no fire. Tried it by just getting a spark by the opening, and the entire bottle turned into a giant fireball. So maybe it is the fuel ratio? Maybe I'm not getting enough oxygen still?

    Try deodorant spray or propane, don't have to worry about atomizing a liquid fuel as with alcohol. But alcohol has higher energy density, so there's that advantage.

    @timmccormack3930 ปีที่แล้ว

    I've had some trouble getting consistent ignition. Even 70% worked fine, and then it stopped working without 95%, and then even that wasn't working so well. I think my piezo might be wearing out?! It's extracted from a pocket lighter. (Need to get a grill lighter to see if that works better.)
    I may have also been having capacitive coupling issues when I was using an old telephone cord (4p2c) for the two wires for the igniter. Interesting failure mode, but not the complete picture.
    Lastly, I've been trying this with a 1L water bottle. Very thin-walled, might be at mild risk of rupture. But I think it also isn't as *rigid*, which might dampen some of the force transfer. Will try to find a soda bottle...

    • @Nighthawkinlight
      @Nighthawkinlight  ปีที่แล้ว +1

      Could be your igniter wires are too long. The spark loses power with long wires. Alcohol can be tricky though. I've switched to using propane if you watch my newer bottle launcher videos

      @timmccormack3930 ปีที่แล้ว

I think I have to stick with alcohol (I'm in the city, people will be less touch about that) but I'll focus on getting the leads as short as possible and see about maximizing the spark. I saw your comment about tinning the spark gap leads as well, and will try that too.

    Years ago 24 ounce plastic bottles you could launch a 12 ounce aluminum can. Manual can opener to remove the top of the can, cut the bottom out of the bottle, put two screws in the neck of bottle for your spark gap. IMA fan of Dr pepper, so I called it a flaming Dr pepper, as the can would still be on fire from the wife's hairspray. Try a degreaser called "quick peel" made with oranges :)
