A mini-rocket that uses water and carbon dioxide as “fuel”. The principle of the rocket is simple; the Newton third law of motion states “for every action there is an equal opposite reaction”. The action is the gas produced by the effervescent when is in contact with water. The gas creates pressure and accumulates until the cap pops out. As the cap have no where to go, the plastic can goes up (the opposite reaction) because the gas pushes it.
1. Remove the Silica gel from the cap and discard it. Do not touch it, do not eat it, do not do anything with it. If fact, DO NOT BUILD THIS PROJECT.
2. Take a piece of the effervescent table and put it in the cap. Be sure the piece of the tablet doesn’t fall when the cap is upside down.
3. Put some water in the plastic can. Do not use too much water because it causes a big mess. The rocket works better just using little water, not even a 1/4″ of water.
4. Put the cap and be sure it is sealed, so no air escapes. If the cap is tight, the rocket will fly higher. Now the “rocket” is ready to be launch. To launch it, just put it upside down and wait until it pops. Remember to take it outside.
It takes about 10 to 15 seconds for the launch, so is plenty of time to get away from it. No kids should be close to the rocket when it is ready for lunch.
