Mentos Bottle ROCKET!

thingiverse

Update 10/10/18: Added modified version where the engines go at a 45-degree straight in the center, rather than back to a 0-degree angle. This makes it easier to print standing. Are you ready for takeoff?! Alright, honestly, I have not tested this thing, so I'm unaware of its working or not. I wanted to design a Mentos rocket that when you drop the Mentos in then it takes off! Zoom! Print in PLA or ABS should be fine. Make sure to put supports on the base, but not in the tubes because you want those clear and clean. The diameter should be significant enough to get good flow through. The small release pin hole (which on the renders is higher, it has been moved lower to maximize capacity of Mentos) is to place a needle or something thin through. I made the holes very small because I don't want my pressure to escape that way, and it will! Be prepared for soda to spray out that way also. You might also want to tie a string to this thing, because it won't be like a grenade when you have a few seconds before explosion, it will be in your face instantly. Warning: Any item flying through time and space is dangerous. Do not do this without parental supervision. Do not do this unless you are a trained professional in a safe environment. I take no responsibility for what you do with this design. I am yelling at you. Leave feedback, upload photos. Please share your experience with others.
