This is a little bit off topic, but also a little bit on topic. Another video for Quintin!!!! Remember when you were telling me about super cooling liquid...well...I looked into this cool idea you were telling me about and I found this video which explains why and how. All I can say is WOW! First I looked up the super cooled coke you were tellling me about and I was sure it was just a magic trick...until now:)
