Homemade Hydrogen Balloons!
Hello guys!
Today I have a new video on how to make flying hydrogen balloons fairly easily at home.
https://youtu.be/qlLYXG6CCAQ
I would love to hear some feedback! Especially if anybody has any suggestions on how to improve this! :-)

Hi ElchScience
I like your method with the water trap, it tends to scrub off some of the NaOH mist in the H2 stream. Nice simple project.
Further in your video I notice you reverted to my old method of collector on bottle top. 
However, call me a wimp but I would hesitate to inhale any home made gas and Hydrogen is very reactive as compared to Helium, I can just imagine some
doing this at a party when someone walks up and lights a cigarette when you are squeaking 
Keep up the good work

Great video, exploding H2 baloons has been on my "to do" list for a while.

I tried this the other day using HCl and Aluminum foil. Unfortunately I tried to be a cheapskate and use a plastic pop bottle, the heat from reaction
warped the cap and created a leak. The leak meant that my wash bottle was fornot, and my balloons were mostly filled with HCl vapors, very sad.
