If you haven't heard of the Mentos Fountain, you've been locked away on desert island for the last year. This relatively simple science demonstration has become a world wide phenomenon. It has spawned hundreds of viral videos (check out this one), new toys (e.g. the geyser tube), and a new world record (click here). Of course, all this attention is well-deserved. After all, who knew you could have so much fun with a 2-liter bottle of soda and a roll of mints. That being said...it should come as no surprise that I would purchase 20 2-liter bottles of diet cola and a dozen rolls of mentos for my son's first birthday. I set up my little "event" in the backyard. Here's how I set everything up:
- I removed four mentos from the pack. Using a small drill, I drilled a small hole in the center of each mento. Yes, I didn't have to use a power tool for this, but it made the whole process a lot more fun. If you don't want to follow my lead, you can use a nail and a little elbow greese to put a hole in the center of the mentos.
- I threaded the five mentos onto a piece of wire (a garbage bag tie works well).
- I drilled a small hole in the center of the cap of the 2-liter bottle.
- I pushed the tip of the wire through the hole in the cap, so that the mentos hung beneath the cap.
- I placed the open 2-liter bottles on a flat surface (e.g. sheets of plywood).
