You know those really great science lessons at school? The ones where the teacher would bust out the glass cupboard and pour funny coloured liquids into each other that would either catch fire, explode or catch fire and explode? Well Plymouth University decided to conduct a similar experiment. Given that they are a higher education institution however, they took it one step further and added a bin full of hapless ping pong balls into the mix.
The lessons you can learn from this are a) if you stumble across a canister of liquid nitrogen, don’t try and store it in a coke bottle and b) if you get turned into a ping pong ball, fear scientists.
