Description:
1. Print recipes for the different types of ice cream and tape them to tables. Lay out ingredients on one table and cans, rock salt, tape on another. Keep ice in a cooler.
2. Explain how the process works. Teens should be in groups of 2-4.
3. Mix ingredients (per recipe) well in the smaller can. Seal the can lid well with duct tape or another strong tape. Place the small can inside the larger one. Put ice and one cup of rock salt between the cans. Pack it very well. Put the lid on the larger can and seal with tape.
4. Weather permitting, try this next part outside. Sitting on the ground, roll can back and forth to each other. Condensation will make everything wet, so wipe off cans as necessary.
5. After 15 min., replace the salt and ice and add any extras (chocolate chips, nuts, candy pieces, etc.) to the ice cream mixture.
6. Seal everything again and roll for another 10-15 min.
7. Open, dish, top, and eat!
