Question

I want an easy guide Jam-packed with tips for making and launching a coca-cola mentos rocket. I need to know how to attach the top (tight or lose). how to launch it (throw up, throw down, throw at an angle, horizontal or vertical) any other little points you can think of please include I need every scrap I can get. I've been off school for a while now and myself and my friends are running out of time wasting ideas. Other suggestions for simlar fun things to do wud be appreciated.

Answer 1

It's a LOT easier than you think:

Step 1 - Buy a two liter bottle of soda (technically anything will do, but traditionalists use Diet Coke) and a tube of Mentos (again, technically Tums and other stuff works, but it's easiest with the Mentos in this case.

Step 2 - Remove the outer sleeve from the Mentos, but leave all the candy still wrapped in the foil tube it comes in.

Step 3 - Open the Diet Coke and drop the whole silver sleeve inside. Quickly screw the cap on tight.

Step 4 - Unscrew the cap slightly until you hear the gas escaping, then violently throw the bottle on the ground.

The orientation of the bottle when you throw it down doesn't matter immensely unless you want it to go in a specific direction. Even if you throw it down sideways, it seems to have a tendancy to end up shooting upward.

Also wear clothes you don't mind getting splashed on! The original experimentors said the only reason they chose Diet Coke was that it wouldn't stain and could be washed out easily!

Hope that helps! Have fun! (I love these things!)

It will depend on what lies past that mountain. Every step will lead you past that mountain, however then all of it have to no longer pass in useless. Its no longer constantly that the hardest of demanding situations offers you the exceptional of outcome. You must understand what lies at the back of that mountain, and best climb if its valued at it. PS: Not constantly must you climb the mountains; typically its well to make use of the valleys.
