[SF Demo] Liquid Nitrogen

Liquid Nitrogen

Many experiments can be performed with liquid nitrogen, and the person running the demo gives a brief explanation of each of them showing a total of four different demonstrations. Starting off with creating a cloud by taking boiling water and quickly dumping some liquid nitrogen into it, then they stand tall holding a flower in their hand. All it takes is a tiny bit for the flower to freeze and just hitting it hard on your hand can shatter the petals. Exploding a bottle seems easier. All it takes is filling a bottle about ten percent full, then placing a cap on it, and then stepping back and watching it explode, and the last thing the demonstrator shows is creating a bottle rocket. This is extremely dangerous, and they advise you to be careful. Taking a plastic bottle and filling it about 1/3 of the way up with water, then adding ten percent liquid nitrogen to it. Then taking a gloved thumb and covering the opening loosely, turn the bottle upside down. The liquid nitrogen will expand and create a bottle rocket.
