The reaction of when a regular mint (or fruit) Mentos is dropped into a bottle of diet Coke can create a fountain of soda. Without a nozzle, you will have a Coke fountain only about 5 feet high. With this, you can have a Coke fountain up to 10 feet! Here’s how to make your own nozzle for cheap.
Steps
Step #1: Cut PVC
Next
- Cut a piece of 1/2" PVC pipe that is 7 inches long and cement that piece to the 1/2" coupler (the small circle in the last pic).
- Now the vertical part of the tee fitting (the larger circle) needs to be cut off with a hacksaw. Cut a piece of the thin plastic to fit over the hole of the "T". Hot glue the plastic to the cut to seal up the hole. Now cement the 1/2" coupler to one end of the tee.
- I am using blue duct tape as a substitute for PVC cement!
Conclusion
I have noticed that diet cola works the best when doing the Coke-and-Mentos explosion. Also, diet soda is less sticky to clean up.
