also, im sure there is a scientific explanation for this, but why did the iron turn black when you grinded it up?

great vid, but u scared the hell out of me when the nail detached from the drill and u picked it up. My brain was like NO, ITS HOT, but i guess i was wrong LOL

You can also use it to make magnetic slime.

Hey, great video ! Can you please telll me the reference of your polymer sheet ? I'd like to buy some for a demo with a class. Thanks a lot !

Wondered about this my whole life. Thank you!

Thx

amazing what people will to save materials

Then put 1875 >15 amp less line lost ask why all at once

Thanks for the video, I was just wondering about this.

Grinder?

I had just noticed that refrigerator magnets are directional, and found this explaining why. Thanks!

Hello, we saw your video, liked it and subscribed to your channel. We are also fascinated by the 3D-VIEW-MASTER and Stereography. We read the texts on our channel to the reels.

My iron fillings that i made at home are dirty from the dirt but idk how to clean it

Thank you sir, just what I was looking for

5:22 can I find the magnitude or the length of each vector and add them up?

thank you!!

people are soo much filled of hate you guys are losers! AMAZING video keep it up...Iwas looking for this couldnt find it anywhere

I am almost positive that this is my old math teacher Mr. Prinz

Dude, you are showing somebody how to slice their thumb wide ass open !

Great content, but please focus your camera properly its giving me a headache

Thank you so much. I had bits and bites of it but not all together. Was very confusing. Now piece of cake!!!!

Where can I buy a view master

carefully cut towards yourself... yeah...

it should fit iphone4 for this red viewmaster.

Man get a better camera that can focus.

sinThetacosTheta = ay*dx/2vi^2 at the end. You completely forgot to square the initial velocity at the end of the problem

Freking easy

they more dyi videos on viewmaster they should try different models put it on youtube.

that perfect fit was phenomenal

Thanks for sharing this. I had an old View-Master that my kids had ruined by letting the switch snap back and now I can use it with my phone.

thanks for the tutorial. i found it easy to attach to a selfie stick with a rubber band

Brilliant improvisation, mate!

I got one for free at version it was a custom star wars one

se ve borroso

I recommend a feature called focus lock.

Now there's an official one!

You magnificent beast! Thank you so much! I was working on a problem exactly like this (canon instead of hose), and was having so much trouble. This was exactly what I was looking for.

thanks that was helpful

Why at 7:36 do you change it to -1/2gt^2, while in the equation above it is +1/2at^2?

Thank you so much!!

Thanks so much for this video. I just received a physics investigation and this is exactly what I need. I couldn't find anything like it that explains it so well. I will make sure my classmates are aware of this video.

Theres 2 angles.. show how you got the other angle value.

GREAT!!!

I had this thought too, time to hit up the thrift store! The Part where you bust out the exacto knife is kinda frightening...always cut away from yourself

much of video completely out of focus

Thank you sir. You saved us a lot of time. Thank you.

Professor McMorran! First of all, thank you for even attempting to do this. I suspect you are not required by the University to put videos on TH-cam of you solving homework problems, so good on ya for doing it. You deserve kudos for the extra effort. Having said that... Is there a manual focus mode on your camera?? I almost puked while watching you solve the problem. The autofocus does not like physics, apparently. Clear! (physics physics) BLURRY(..?) Clear! (physics physics) BLURRY...

Dat ladder!
