Real rockets are launched when fuel is burned. This burning of fuel is a chemical reaction.
We found out that when vinegar and bread soda are mixed together then this also causes a chemical reaction which gives off a gas called carbon dioxide.
We used vinegar and bread soda to show what an exploding volcano looks like, we made a small rocket launch with a small pop, and we tried to launch another rocket filled with vinegar and bread soda. (This rocket didn’t fly because there were a few little holes in in. That meant that the carbon dioxide couldn’t build up in the rocket and cause it to fly. Teacher is going to try and mend it again with duct tape and maybe we can try again next week). We could really see the bubbles forming in the rocket.
