Feeling Pressured

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure. A learner (at least 100 lbs) will step inside an extra large trash bag, while another reduces the air pressure in the bag slightly with a vacuum cleaner. The bag will squeeze the occupant due to the differences in external and internal pressure.
