Mentos and Diet Coke Rocket

Step 4 Liftoff

If slamming process went correctly, the cap of the 2 Liter will hit the ground and break off, diet coke will then be forced out of the neck creating thrust forcing the bottle off the ground in an upward motion. This thrust is greater than the weight (Weight=Mass*acceleration due to gravity) of the bottle(Yes weight is a force) so it propels the bottle in an upward fashion at a great rate of speed reaching a terminal velocity that gives it the capability to reach heights of 40+ feet!

dude u can get more thrust if u take 6 mentos together with tape then tape that to the cap believe me u get ALOT more thrust like double even triple the height u wrote good luck -popbottle

Ok first of all, terminal velocity is the maximum speed an object can FALL, and is the average between the force of wind and the pull of gravity. How can and object with propellent going upwards, reach terminal velocity? And also a bottle can go much higher, you must have had horrible luck.
