This Polar Bear Science Experiment is an activity I always enjoyed with the students in my classroom, and now in recent years, we’ve done in it in our homeschool as well.
After they remove their hand from the water, cover the glove on their hand with as much Crisco as you can spread on it!
This may be a little tricky because their glove is now wet, so if you feel like it’s too much of a headache, you could have the student put on a fresh dry glove and then cover that in Crisco.
