HOW MARINE ANIMALS STAY WARM
Dive Deeper Weeklong Challenge #2
3 - gallon or quart size zippered plastic bags
1 large container of lard or shortening
2 large containers of ice or ice water
Optional: Heavy rubber kitchen glove
Here's what to do:
Step 1: Scoop fat into two of the zippered plastic bags. Spread the fat inside the bag so that it fills the bag and is about 1 inch thick. Seal the bags.
Step 2: Lay one bag on top of the other and tape three of the sides together making a "mitten."
Step 3: Slide the mitten into the third bag with the open side of the mitten facing out of the third bag.
Step 4: Put the mitten into one of the containers of ice, or ice water.
Step 5: Put one hand into the mitten and put your bare hand into the second container of ice.
Optional Step 6: Use a heavy rubber kitchen glove for the bare hand. If a lot of people are doing this activity this will help keep the demonstration area dry.
