Group+3


 * TOPIC IDEA FOR PROJECT: The effect of the temperature on the height the spout of coke reaches with a coke and mento reaction.**

‍GROUP MEMBERS: David Hayman, Joshua Himes, Gabe Perry, Kyle Claassen, and Ben Finn
__MATERIALS:__ Diet coke, mentos (original mint kind), angle gun thing (already forgot name), timer (for physics purposes), thermometer, cooler (to help maintain coke temp.), a stable base to put soda on, mento dispenser

__INFORMATION:__
 * Some scientists claim that the reaction is a physical one and not a chemical one
 * the carbon dioxide already in the soda it just forms up on the surface of anything you drop into it ( ex: when you drop a straw into a glass of coke you will notice that there will be bubbles forming and formed all over the straw, it has nothing to do with a chemical change it is just a break in surface tension
 * Water is attracted to other water molecules forming a mesh around the CO2 gas keeping it from expanding and escaping
 * It takes some energy to break this "surface tension", which is provided by the mento's gelatin and gum arabic dissolving
 * original mint mentos work best because the pits in it provide more surface area or "nucleation sites"
 * physical changes vs chemical changes
 * chemical changes are the changes within the very substances. The molecules themselves are changing
 * physical changes there are changes in how it looks feels or smells but the very substance has not changed. It is the change of how the molecules are arranged
 * Reminders:**
 * Have 3 different temperatures, 3 trials each
 * Come up with good way to get mentos in quickly
 * Kinematic will be used (velocity and such)
