What goes up must come down

We've all created our own rockets with Mentos and bottles of Diet Coke, right? Now we've taken your backyard science to the next level with our Vertical Landing Mentos & Diet Coke Rocket.

The first bit is the part you're familiar with. After you've set up the four-bottle rocket configuration, the Mentos combine with the Diet Coke in the main 2 liter bottle, providing the "first-stage engine thrust." The chemical reaction of the CO2 being forced out of the solution when the nucleation on the candy's surface starts is what provides your liftoff, as per usual. Foam. Force. And a jet of soda, which sends your rocket 20-30 feet in the air. 

Here's the new part. The aquarium tubing, which provides a link from the main 2 liter bottle to the three smaller side bottles, then provides some stability in this all-pneumatic system, releasing its own sodas' CO2 in turn. Those side bottles help to balance your now falling rocket enough for safe reentry and landing. Protip: Make sure you have the same amount of soda in each side bottle to ensure your vertical landing's success. Send us Action Shots of your Vertical Landing Mentos & Diet Coke Rocket on the landing pad to show us your skills!
