If you had a boat, what would you call it?
RMS Davemania. Been a fan since 2016. Keep it up!

THE GREAT DAWSON
Bro bro 123
Neat project. I think it alternately pushes water out and sucks it in both of the tubes. At least that's how most of the pop pop engines I've seen work. Other wise, we'd probably just use heating loops in pipes instead of pumps and this would be called a thermosyphon. We use thermosyphon cooling on our refrigeration compressors at work but one end is slightly higher than the other so that the heat creates bubbles and makes the liquid refrigerant less dense on the heated side which causes the incoming side to be heavier than the outgoing side. In a pop pop engine, the water boils, creates steam, pushes water out of the tubes, creates a vacuum in the boiler, sucks water in (all tubes) and starts the cycle over. In refrigeration terms, you're riding the saturation line of the pressure/temperature chart for water- quickly changing state from liquid to vapor and back.
Me : I am gonna throw all these waste in dustbin.
Dave : No, that'll be my next Episode. *PRETTY COOL HUH*
DaveHax: This copper pipe measures 3/16 of an *inch* in diameter and cut a length of aproximately 38 *centimeters*
Me: **Confused screaming**
Why, it says 38 cm
There's inches and davehax is using imperial and metric system
Aaa aaaaaaaAAAAAAAAAAAAAA
He be using the whole metric system just to get to the simple measurement 😂😂😂
🏆🌍🐱
To help bending the tube without kinking:
- leave it a little longer than it should be
- squeeze one end shut
- fill it up with very fine sand or salt
- squeeze the other end shut
- bend
- cut off both ends
I personally adore your egg slicing and hot knife cutting videos please please please do more because we haven’t seen them in a long time. I love you Dave.
That's pretty ingenious and I'm totally impressed
I Have watched you since 2015 and youre still AMAZING
Thanks, glad you like my vids :)
@@DaveHax I was watching u from 2016 and I loved ur clothes folding technique
Same
I have since 2014
same !!
Recycling, the best word I can hear in your content.
*wishes DaveHax had been my science teacher in school*
same same
Great science experiment Dave!
Amazing diy project !
It you bent both ends in the same direction would it just go forwards?
Put a transparent cylinder around the outside with colours painted on or pictures in a sequence that makes an animation as the boat turns. Could make an interesting holiday decoration.
oh cool!
I learned these boats exist by watching Ponyo as a little kid😂
I said go to jail
Wish I would have found you sooner, you make such good content.
Just seeing polystyrene makes my skin hair rise and cold shivers go through my body. And then to just imagine all the grating sounds that cutting the polystyrene makes. Causes shivers to go all the way through my body.
Nails scratching down chalk board,
Rough hands on nylon clothing,
spiders crawling over you.
Just a few more things that might freak you out :D
@@izzzzzz6
Nails on chalk board aren't as bad as polystyrene sounds does. But spiders definitely would do that as I have fear of spiders.
Wow, that's amazing!
This is awesome!
OMG I love your vids! It all works! thx!
This is great for romance xD just imagine some one needs to make a romantic but scientific dinner just imagine the look on their face xD
Pretty cool, Dave.
Me: mom can I make this boat
Mom: NO
Me: putt putt why not
I actually will do this because this is so cool
Another encouraging video
Dave I've been with u for a long time and love your videos hope u have a good day and good job Keep up the good work I subbed and hitted the notification bell you are my childhood hero thank you
Well, look who's back from the dead! Welcome back, DaveHax!!
Pretty cool
That’s cool I like it 👍gets the mind thinking.
Pretty Cool? Hell Yeah!!! That's awesome Dave, 👍🏻💖🏆🥂
lol Glad you like it!
Awesome video Dave! Been a fan since 2014! So awesome to see how much you have grown!
Thanks for your support :)
@@DaveHax np
@@DaveHax haha hello!
Long time since you last Pop Pop boat 😁👍
Davehax can you heart this comment I’m a og fan
Wow
How did that work
Pretty cool...
omg thats so cool!
Glad you like it!
Great vid
I love your video's 😍😍😍
Thanks very much!
خیلی مفید.😘
Love your work
Thanks very much!
I would call my boat The Titanic XD
Pretty cool hu!
Good boat
Very Cool
Agree with comment earlier. The steam must force water out of both exits and the water in the pipe must all turn to steam. Eventually the pipe will get hotter and hotter as there is no water to absorb the heat. Great video.

I've been watching since I was 6 Im turning 14 on the 29th
I'm showing these to my son who is 2 years old, he loves them.
I've been following his channel since 2014 when he made Travel Hacks
Amazing
Good.
E Polytechnic.
A technical channel.
You spin me right round baby, right round like a record baby, right round round round
Thank you because I've received creative scientist at school because of you😳
This man has too much time on his hands, well we all do but when it’s a normal day he does (when it’s not a pandemic)
haha
I love davehax
"spinning pop pop putt putt boat"
Me: what the heck is thay
i swear this is the longest video by Dave ngl lol
I would like to make a boat for a long time and now I know how to do.
I love it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! This reminds me of the boat that is on the movie, "Ponyo"!! Can you make one like that? One that moves forward?
yes, look up pop pop boats
@@Jojo43O9 Thank you 👍

PRETTY COOL HUH
I don't get it. How is the water sucked in, when heat makes things expand? Wouldn't the water be pushed out of BOTH ends?
Water is indeed pushed out of both ends, and when the pressure inside the boiler drops water comes back in through both ends - not in one and out the other as alluded to in the video. Wikipedia has a good summary of how these engines work: en.wikipedia.org/wiki/Pop_pop_boat#Principle_of_operation
Why does T series have more subscribers than davehax ????
Because T-SERIES ALSO SUBSCRIBED FOR DAVEHAX
BIG FAN BRO FROM INDIA🇮🇳 DEVEHAX
Be cause sub bots
* In Indian accent *
Well first of all because of the TH-cam algorithm
I like it
Pretty cool hah
Can you use this engine and use it as a substitute for the putt putt boat you build awhile ago
so as long as the candle is there and heating the pipe it will infinintly go
You: let’s recycle the foam.
Me: Ya said it won’t go to landfill but some still does!!🤣🤣🤣🤣😂
Go to jail
Very creative👍🏻Much better then it going to landfill😕💖😊
@4:47
Ummm that doesn't seem right? Which side of the pipe sucks vs blows?
I would think both suck and both blow of the same amount. Which would still allow the spinning
nice
you could put a decoration over it and make it look like it's dancing
It is early spinning light house principals?
im back to HAX!!! I have nothing to do during this pandemic. So DaveHax is the answer to my key. Unfortunately i do not get all those foam packaging as much. Postmaster is too scared But i find floral rings.
0:07 don’t you hate it when you receive lots of excess packaging that just ends up in landfill
How does the water choose it path of direction? Is it random each time which way the water travels through the pipe or does it just vary and become random each time?
You should do the same but with a boat hall
good
If fresh water is sucked in one end and pushed out the other end, shouldn’t the pipe be angled differently. Seems as shown if one pipe is pushing and one pipe is pulling, they would work against each other?
you are correct. his explanation was incorrect. water exits both ends of the pipe simultaneously, as the expanded steam forces it out from the tube in both directions. eventually the steam has expanded as much as it can, the inside of the coil cools just a bit and the low pressure (vacuum) sucks water back into the pipe from both ends. the sucking in of water is multidirectional, whereas the exiting of the water is in one direction (resulting in different force vectors along the plane of the exit pipe)., and i believe this is why the forces do not just cancel.
Michael Jackson moon walk😅
Nice video bro👍👍👍❤️❤️❤️
Whos here but wont make this 😑
Me first
The second reply in here in 2 years
Kkkkkkkk
Kkkkkkkk
Can you show if the water is really going in one end and out of the other? It seems unlikely
I’ve been watching since 2015
Are you coming to Essex,Barking and Dagenham,RM96AF??????
How long did it take to heat up the bowl of water? Did you happen to gauge the resulting temperatures? ☺️
how come one end of the pipe squirts water out and the other does not? what determines which pipe does this?
Pls do how to make a 100% legal non nukeler warhead that makes a mushroom cloud
DON’T PLAY WITH FIRE, KIDS!
For those who don't have a glass bowl, a properly sanitized toilet bowl will suffice as an appropriate vessel
WOW! Add a solar panel and away we go! would that work?
Pretty spin me right round (singing) right round
Pretty *boaty* huh?
I Know You see a Video King Of The Random
if it's sucking water in one end and pushing out the other, don't you want them facing the _same_ direction?
Dave, that was a mini steam engine
Better than 5 mins craft
Not a pop-pop boat. But a good design.
Where is the link.
that blue disk is very pretty... what is that for?
😂
Reminds me of Ponyo
Hello guys
Quick question,
When you reach 5 mil can you start using your real voice (unless this is your real voice I think its a computer voice...)
P. S. I love your channel and subbed!
lol its his voice
It's his because you can hear him take a small breath when speaking
