Mentos-and-Coke Propelled Skateboard

Prepare yourself for coke + mentos awesomeness!
This is an easy-to-make instructable on how to have some fun with Mentos and Coke.

Step 1: Get Your Materials

• 1 Two-liter bottle of carbonated soda (preferably diet coke)
• A skateboard (or any platform with wheels)
• Duct tape
• A rubber cork/stopper (we used 15/16th inch by 3/4th inch). Available at any hardware store.
• 5 Mentos

Step 2: Prep the Mentos

Tape the 5 mentos stacked together with a vertical piece of tape so that they fit in the bottle

Step 3: Prep the Cork

Tape the strung mentos to the bottom of the cork.

Step 4: Prep the Skateboard

Tape the bottle to the skateboard so that the neck of the bottle sticks out the back.

Step 5: Insert the Mentos

With the coke facing up, unscrew the cap. Slowly insert the cork with mentos attached so that the mentos don’t touch the coke immediately.

Step 6: Prep for Launch

Flip the skateboard facing the direction you want to launch while HOLDING THE CORK TIGHTLY ONTO THE BOTTLE. Shake if possible.

Step 7: Watch It Launch

Release your grip on the cork and watch it launch!
