Printed on top of the exhibit are the words "How Strong Is A Vacuum?" The exhibit was a four-foot high wood box with a metal handle on a cylinder. The handle weighed one pound, then you turned on the vacuum power under the cylinder. The sign said "Press the vacuum button and pull with all your might!" Okay.
I turned on the vacuum. I bent my knees and straightened my back and grabbed the handle with both hands. My friend
It lifted off the ground, so I stopped pulling. But it didn't lift straight, just up at one corner. When I let go the exhibit stayed up on the one threaded bolt at an obviously improper angle.
I caught myself patting the broken exhibit like it was a bird whose neck I had broken and I was trying to position it into a lifelike shape before leaving.
Then my friends decided that I had learned enough science for the day.
But I did learn how strong a vacuum is. 0.8 Basils.
I am now a reference standard.
