'Blubber Gloves' is an experiment designed to simulate how blubber works to protect some mammals (like seals) from freezing during the winter. It is also a great use of all that Crisco-brand shortening you have lying around....
To conduct this experiment:
'Blubber Gloves' experiment video...
Put about 2 cups of Crisco (or other vegetable shortening) into a gallon-size zipper bag.
Put your hand into a separate gallon-size zipper bag and insert your bagged hand into the bag of shortening.
Spread the shortening evenly between the two bags, avoiding the topmost portion of the bags
Fold over the lip of the inside and outside bags and then duct tape around the folded lips
Have children put their hands into a bucket/bowl of ice water without any kind of glove until it becomes uncomfortably cold
Have children then put on the Blubber Glove and see how long they can hold their hand in the ice water
