Re: hydrogen balloons

But we had a normal size balloon that didnt go onto the conical flask properly. I did it again after, with less Al and NaOH an...

Re: Science Week

The problem with Steve Spangler is that he does not write in the chemical and preportions that he uses. Probley a liability thing, but it makes his site very interesting but not very practical.

Re: Science Week

what would you put into the watermellon to make it explode like Steve got them to??? :?

How do you get the balloons that full of H2? Any of the things i know how to do ends up with not enough of a reaction to fill the balloon? :cry2:

What happens with the Glycerin and KMnO4? :oops:

But the gentle persuasion from a rubber mallet and WD40 sounds like the logical course of action. However i think that i will get the gas guy i...
