Bottle coke diet mentos rocket
You can also increase the effect by adding more surfactants to the soda when you add the Mentos, like adding a mixture of dishwasher soap and water. The cap should be securely on the bottle, but not closed too tightly. Shake it so that the Mentos fall into the Diet Coke, and then keep shaking. They should look just as they did when they were still in their original packaging: stacked on top of one another like a roll of coins. Fasten the Mentos cartridge into the bottom of the Diet Coke cap. Place the Mentos cartridge, sticky-tape side up, into the soda cap and press down to fasten it there. Bubbles will continue to form on the porous surface and the process will repeat, creating a nice, foamy geyser. Attach the rolled tape to the top of the Mentos. Another factor that contributes to the size of the geyser is how rapidly the object causing the foaming sinks in the soda. Wearing goggles will not only protect your eyes from the soda-Mentos concoction, but also from any other debris (for example, the lid) that might fly out from the bottle once it hits the ground and explodes. Combine Diet Coke and Mentos, and the result is explosive—Diet Coke shoots out of the bottle like a miniature, sticky Old Faithful. Cut a 3-inch (7. Daven Hiskey filed under: Big Questions, Food, Food, science. Put the cap on a flat surface, with its inside facing upwards. 2-centimeter) strips of masking tape. Place the strips of tape on a flat surface, with their sticky sides facing up. Cut 2 4-inch (10. Each Mentos candy has thousands of small pores on its surface which disrupt the polar attractions between water molecules, creating thousands of ideal nucleation sites for the gas molecules to congregate. Find a wide-open space to build the rocket in.
Lay the Mentos on to one of the 4-inch (10. 2-centimeter) strips of tape. Another method is to throw the bottle at a side angle so that when it hits the ground, the ground knocks off its cap. Edit Article How to Make a Diet Coke and Mentos Rocket. Place the other 4-inch (10. 2-centimeter) strip of tape on top of the Mentos.

As the rocket is more of a fast-acting affair, you might want to go for Mint Mentos. Coffey and company discovered that the ingredients in the Mentos and Diet Coke and, more importantly, the structure of the Mentos, allow carbon dioxide bubbles to form extremely rapidly. A popular and effective one is to throw the bottle high up into the air and let it fall on to the ground (preferably hard ground, like cement). Tonya Coffey of Appalachian State University and her physics students published a paper on the phenomenon in the American Journal of Physics. The reaction is so intense, you can make a rocket propelled by the resulting geyser. In addition to that, the gum arabic and gelatin ingredients of the Mentos, combined with the potassium benzoate, sugar or (potentially) aspartame in diet sodas, also help in this process. Be sure to leave the sides of the Mentos exposed. When the bottle falls hard against the ground, the cap flies off and the pressure releases, launching the bottle up into the air. Diet sodas produce a bigger reaction than non-diet sodas because aspartame lowers the surface tension of the liquid much more than sugar or corn syrup will.
