Did you know that you can make rockets out of soda bottles?
NB! This experiment must not be done indoors. Experiments must always follow the safety rules that apply to laboratory experiments. Remember protective gloves and goggles.
You need:
• Safety goggles and gloves
• 0.5 l Coca cola bottles
• Liquid nitrogen
• A launch pad (for example, part of a gutter)
Recipe:
1. Wear safety goggles and gloves
2. Drink some of the coke
3. Carefully add liquid nitrogen to the soda
4. Turn the bottle very quickly upside down and place it in the launch pad. We used a part of a sloping gutter as a ramp
5. The soda whizzes away like a rocket!
Liquid nitrogen (minus 196 degrees Celsius) quickly releases all the carbon dioxide gas in the coke bottle.
According to Newton's third law, the coke that squirts backwards will have an equal force forward. This power makes the rocket take off at high speed!
