Mr. Faherty's class and Ms. McLoughlin's classes together launched fizzy rockets.
We had to fill the rocket up 1/3 full of water.
We added a fizzy tablet, popped on the lid, counted down and waited for the explosions.
It was very exciting.
Some of our rockets launched higher than others.
The power to launch the rocket comes from the chemical reaction between the water and the fizzy tablet, causing the gas carbon dioxide to form.
This builds up under pressure and eventually the pressure becomes too strong and the rocket flies off.
A fantastic chemically powered rocket!
