making rockets!

Today we made rockets, we had to make the rockets go as high as we could with the resources we had which were:

•  rocket powder (baking soda)
• rocket fuel (2 T of citric acid and water)
• tin foil
• canister

First of all you cut a square out of tin foil and wrap it around your finger to make a small cup, then fill it up half way up with the "rocket powder", secondly you get your canister and fill that up a quarter full of "rocket powder" and finally add the "rocket powder (in the tin foil) to the liquid and watch it explode!

Q: what worked well?
A: less "rocket powder" and "rocket fuel" worked better probably because there was more air to build up pressure to make it pop faster and fly higher.

Q: what didn't work well?
A: more "rocket powder" and "rocket fuel" didn't work as well most likely because there wasn't enough air to build up pressure to make it pop as fast or as high.

so all in all less powder and fuel works better and too much powder and fuel doesn't work as well.
