What an awesome show. They did experiment after experiment trying to find something cooler then mixing diet coke and mentos. The Methane bubbles and fire was pretty awesome but nothing beats the Diet Coke and Mentos.
The day after me and my family saw this show we bought 4 2 liters of diet coke and 2 boxes of mentos and mixed them in my front lawn.
If you don't know what I am talking about. If you get mentos and put like 4-5 of them in a 2 liter of Diet Coke...well try it and find out. Don't worry it is completely safe. You might get diet coke on you. But make sure you put the mentos in fast.
