I mentioned last week that the cola bombs were the highlight of Mikey’s birthday party. They were so much fun! Cola bombs (aka: Cola Geysers, Mentos Bombs, Soda Rockets, etc.) are easy to make and all over the internet. A few of you asked me last week how we made them, and while I can direct you to the thousands of pages and youtube videos with directions, I thought I would toss out a tip we learned from Mikey’s 1st grade teacher the day of the party. It’s a total lifesaver, especially if you’re setting off several bombs at once or in succession like we did. This tip also allows little ones (preschoolers) to participate without getting diet coke in their eye. Probably.
You will need:
- 2L bottles of Diet Coke (Diet Coke will give you the most height)
- A roll of Mentos for each bottle. That’s 12 Mentos if you happen to have them loose or bought them in bulk
- Scotch tape
Most tutorials suggest you use a card and tube to funnel the Mentos into the Diet Coke. You place the card on top of the bottle, the tube on top of the card, and then quickly slide out the card like a trap door and let the Mentos fall in. That works, but not well. We found the paper tubes were flimsy in little hands and not all the Mentos made it inside the bottle. Sometimes the bottle falls down. You have to be quick and limber! There are kits you can buy online, but…no.
Scotch tape to the rescue!
First, go outside! You don’t want to do this inside, though there are plenty of pranksters on Youtube that recommend otherwise.
Next, unroll your pack of 12 Mentos and gently place a strip of scotch tape along the top. You can also lay the tape sticky side up on a hard surface and place the 12 Mentos individually. They will stand up!
Place another strip of tape on top and lightly press the candy into a makeshift cylinder. You want the tape to barely hold the Mentos in place. See how only a miniscule portion of each Mentos candy touches the tape, and that two sides are completely clear of tape? You need plenty of surface area for the Diet Coke to seep in and around the candy.
Carry your roll of candy like a baby bird to your open 2L bottle of Diet Coke. If you want, you can spill out about 1 cup of the Diet Coke on the ground. Your bomb will be smaller and it will give little ones more time to run.
Drop it in. The scotch tape makes it pretty simple, but you still have to beat feet once the candy hits the soda!
Shall we try that from another angle? Yes, lets. Thanks to the scotch tape, 5 year old Nicholas can be in charge of setting off the Cola Bomb.
4th of July is on Wednesday, so you all have to do this with the kids and the adults. We set off these bombs in front of our neighbor’s tree. She laughed and laughed, partly because it’s fun to see something harmless explode on purpose, and partly because the joyous screaming and dancing by Mikey and Nicholas was infectious. “You guys just made my day,” she said as she walked inside, still laughing. I believe it. You just can’t be in a bad mood after watching soda shoot 15 feet into the air.
