instead of a film canister, I used a plastic soda bottle. It went way up in the air probably 1200 ft.

Messy, went off in my hand. Then I put the bicarbonate into an empty paper sugar pack. 1 TB vinegar in canister, drop in the packet, shake & set down. About 10 seconds canister popped up higher than the garage roof. About 25 feet!

I found that using a semitransparent film canister with a push-in top works best. Fill half full with water and add 1/4 to 1/2 Alka-Seltzer tablet and the top shoots 20 feet in the air.

I read that if you make a paste of the baking soda with water, you can pack it into the lid "bowl". Then, pour the vinegar half way up inside the film can. Place the lid on carefully and push down gently to seal it. Shake and set it down. This gives you the time needed to step away. I have used this method with my classes and it works much easier than trying to get the lid on after the substances have mixed!

It took a long time to get good results with baking soda and vinegar because I did not know how much to mix. Then I also tried it with a different fuel. I used an effervescent cold tablet that my mom bought and water. Just stick in the tablet (I even tried it with a fourth of a tablet and it went about 6 feet high), then dump in a little bit of water and quickly stick the lid back on and set it down. The cold tablet was easier and it was awesome to watch!

My flight was about 23 -24 feet. To me it worked better with less bakeing soda and a little more vinegar.

When I did this experiment it shot up like 50 feet in the air! And then it came crashing down.

Priyank, age 10 of Brampton wrote:
I did it and it flew like 20 feet. Another way to do it is put vinegar in the film canister then get a piece of toilet paper aand put baking soda in then open the film can and put the toilet paper in. So that way it wont blast as fast so u have time to run.

I tried fifteen times and it didn't work. I couldn't get the lid on quick enough. Three times it went boom but I was still putting the lid on.
