The photos below are from a recent Sophomore Natural Science Class, taught by Dr. Sean Collins. œWe had just finished reading Pascal™s treatise ˜On the Weight of the Air,™ in which he disproves the age-old claim that ˜nature abhors a vacuum,™� Dr. Collins explains. œHe shows that all the phenomena attributed to ˜nature™s abhorrence™ of a vacuum can be much better explained by the weight of the atmosphere. So we did an experiment to replicate Pascal™s observation that the weight of the atmosphere will hold water in a plastic tube up to a height of about 29 feet, but not higher.�

As for why, in some photos, he is holding a tree trimmer, Dr. Collins adds, œWe were using the pole to hold the tube up to different heights ” not for pruning trees!�
