One of the most popular experiments of modern times is the Diet Coke and Mentos Geyser. Made popular by Steve Spangler, this experiment is a lot of fun and sure to amaze your friends and family (assuming you do it outside rather than in the living room).
What you'll need:
- Large bottle of Diet Coke
- About half a pack of Mentos
- Geyser tube (optional but makes things much easier)
