Want to make your own carbonated gas rocket? You’ve probably seen a Coke Mentos Geyser already on the Internet. Just drop a few Mentos into a bottle of Diet Coke and you’ll see a violent Coke and Mentos chemical reaction resulting in a giant 16-foot fountain of foam explode out of the bottle.
Although that may sound somewhat exciting, the Coke and Mentos Geyser is the boring “science teacher” version of experimenting with Mentos and Coke. Here’s how to make a Coke and Mentos Rocket capable of going 100-feet into the air.
How To Make A Coke And Mentos Rocket
If you really want to unleash the carbon dioxide power in a 2-liter bottle of Diet Coke, try making a Coke and Mentos Rocket. Here’s how.
- Buy a 2-liter bottle of Diet Coke and a roll of Mentos. You can use any soda but room temperature Diet Coke for some reason works the best.
- Find a big open area to launch your Coke and Mentos Rocket. Don’t do it indoors. Trust me. I saw some idiot do this in his garage and he immediately regretted it.
- Slide the paper cover off the Mentos (leave the foil wrapper on) and slip the roll into the bottle.
- Quickly cap the bottle and shake it.
- Gently unscrew the cap, just a little, until you start to hear fizzing.
- Throw it down and cover your face! It’s actually a really good idea to wear a helmet.
Other Variations Of The Coke And Mentos Rocket Experiment
People love experimenting with Diet Coke and Mentos. Some of my favorite experiments include the Coke and Mentos Condom, Coke and Mentos Balloons and Mega Coke and Mentos Rockets with 5-gallon water jugs.
Coke And Mentos Condom Explosion
Heather LaCroix, the Internet celebrity famous for her funny online redneck videos, tried a variation of the Mentos and Coke experiment using a condom.
Coke And Mentos Balloons
These guys took 20 bottles of Coke and Diet Coke and filled them all up with Mentos. However, their water balloon execution went horribly wrong. It’s still interesting to watch in case you wanted to try an experiment of your own using balloons. Sealing the cap is a critical part of the experiment. You need to build up enough gas in a vacuum to create the explosion effect.
Mega Coke And Mentos Rockets With Water Jugs
This is another example of what not to do with a Mentos and Coke experiment. It takes a lot of Coke to fill up a 5-gallon jug. Make sure you are using enough Mentos in your experiment and account for gravity. These guys didn’t.
