These are short, science oriented videos that don't fit neatly into other categories. Many are just for fun, as I learn more about the world of video.

that is awesome!
that is just sooooooooooooo awesome! if you have a baloon filled with carbon dioxide and then put your mouth on the nozzle and let go of the neck of the balloon and let the carbon dioxide go into your mouth and then talk, your voice will sound all weird! thanks for another cool video!
Floating bubbles sink
And if you are able to keep your floating bubble intact it eventually sinks lower and lower as the CO2 permeates through the bubble wall and makes it heavier(I think). The colour/color of the bubble film goes golden as the bubble wall gets thinner. Great to watch!
RE: Floating bubbles sink
Great comment! Have you tried it with dry ice? As they sink, they eventually touch the dry ice and will sometimes freeze instead of popping.
So cool!
Thanks for being so clear every step of the way! I've tried it before but without success, not realising where I've gone wrong. Now I know why and will be keen to try this out again. Thanks!
Problem
I can't see the video, the screen just goes black, I have vista.
Re: Problem
It sounds like you are using Internet Explorer 8. Turn on "Compatibility View" and the videos will play with no problem.
Thanks this is great!
Thanks this is a really great experiment with simple products that young children can enjoy. Teaches them that things are there that you can't see!

Bubbles not floating
The bubble maker added too much liquid to the bubbles, making them too heavy. The bubble wand added less liquid, so the bubbles floated.
bubbles not floating
so why didn't it work with the bubble maker?
