Alka-Seltzer Rocket

Alka-Seltzer RocketWhat happens when you have a build-up of gas? Please don’t answer that question! The gas in question is carbon dioxide and the explosion is nothing short of fun. This experiment uses film canisters and Alka-Seltzer to create a rocket. Warning: It’s impossible to do this activity just once. It is addicting and habit-forming. Proceed at your own risk!

I’ve been doing this project since i was like seven but i still LOVE it. I have done other things as science experiments such as rockets and methonal cannons witch are better but this one is the only on I can do in my house! :)

I have done this trick before. No one really expects it to work when… BOOM! That thing can launch like 30 feet!!

I love this experiment, I’m using it for my science experiment on chemical reactions. Thanks!!! :)

Whats the exact or the best ratio for the highest launch

Maybe other people can share their experience as well. The results are all over the place because of the many variables (water temperature, how tightly the cap fits, which type of film canister you’re using, etc.). Using the Fuji canister and room temperature water, our students seem to gravitate towards a film canister filled a little less than half full with a quarter of a tablet of Alka-Seltzer. But again… it’s hit and miss.

Best of all, you can see how great this simple experiment is for collecting, organizing and comparing data.

Thanks so mUch I need to know ASAP!
lol:P
P.S
And when was it built/created? and who created and built it?

In my chemistry class I made an Alka-Seltzer Rocket and I learned how Newton’s Law Motion was discovered by a chemical reaction.

I need to know what the best formula is for the best launch. Like how much water in ml and how much Alka-Seltzer in grams.

this is awsome how can you do that

One for the dangerous but fun category. My other favorite sort of rocket is the match rocket – made by placing 2 matches end to end and rolling in silver foil – really excellent!

I did this same project at my school a am doing it for my seventh grade science project

ok question. The more alka seltzer u put in the bigger the chemical reaction?
i need the answer ASAP!!!!!

Changing the size of the alka seltzer will change the result. You should experiment to find out what produces a bigger and smaller reaction.
