The legendary Mentos Rocket is a fun project you can easily partake in (as long as you don’t mind gambling with the likelihood of being covered in soda!)
Here’s what you’ll need:
1 liter of (warm, not cold) Diet Coca Cola
1 package of mint Mentos
Step 1: Start by letting your soda come to room temperature. Why diet cola instead of regular? Because diet has more carbonation so it’s way more exciting than regular.
Step 2: Once you have all your supplies gathered, begin by cutting 2 strips of masking tape, each about 4 inches long.
Step 3: Line up about 4 or 5 Mentos on one strip of masking tape like a stack of coins, making sure you leave some space on either side of the Mentos line. Then place the other strip along the top.
Step 4: Cut another strip of masking tape 3 inches long and roll it around your fingertip, sticky side out. Place it on top of the Mentos line to complete your Mentos cartridge.
Step 5: Fasten the Mentos cartridge to the bottom of the soda bottle cap.
Step 6: Wrap any loose tape ends around the bottom of the Mentos cartridge.
Step 7: Carefully load the Mentos cartridge into the soda bottle, but don’t screw the cap on too tightly. If the Mentos look like they might touch the coca cola, you can take out a few Mentos before you proceed.
Step 8: Once the cap is on securely, shake the bottle. The rocket is now ready for lift off.
Step 9: There are several different ways to launch the Mentos Rocket, we decided to let the magic happen by placing the bottle on a foldout table. Note: make sure everyone is standing back so they don’t get hit by the soda bottle if it’s a really big explosion!
Step 10: Marvel at the spectacular event you have made.
