desired thickness, remove bag from ice mixture. Wipe the outside of bag with rag or dish towel to remove salt. If you do not do this, you will have salty ice cream :( - Open your ice cream, pour into dish, and enjoy!

Ice vs. Rock Salt

What is the secret with Rock Salt?

• Rock Salt (or even table salt) lowers the freezing point of water into ice.

• It makes the ice very cold. • It simulates a freezer so that

the cream mixture will solidify and make ice cream.

• This is called “Freezing Point Depression”

Why is salt spread on roadways during a winter storm?

• Salt messes with the freezing point of water.

• If it is freezing outside water will turn to ice.

• Salt helps water stay water by lowering the freezing point.

• Water will stay water longer so that drivers can drive on water rather than ice.

• Ice has less friction and can be very dangerous!

Antifreeze and Coolant

• Antifreeze results in Freezing Point Depression• Coolant results in Boiling

Point Elevation • Ethylene glycol is the

active chemical in this antifreeze/coolant product.
