Interesting Stuff

Merry Easter, all! Zombie Jesus may not be real, but we can honour him anyway by watching videos of Zombie Dog Head, which is real. Though I should first post a WARNING: THESE VIDEOS ARE VERY GRAPHIC. The first one shows organs and body parts that have been dismembered. The second shows a dog getting killed (and then brought back to life; there is a happy ending!). Seeing early prototypes of the life support systems that hospitals use is fascinating!

My frisbee claims it is 175 grams, but it certainly doesn’t feel like the regulation weight. Consequently, I wanted to weigh it. The problem? I don’t have a scale. However, I have a bathtub, a whiteboard marker, a large bowl, and a bottle that claims to hold 237 ml. I fill the bathtub partway, and put the bowl in it. I fill up the bottle and pour it into the bowl, and then mark on the bowl where the level of the bathtub water is. I empty the bowl, put the frisbee in it, and mark the height of the water on the bowl again. I take the frisbee out of the bowl, and mark the height of the bathtub water on the bowl when it’s empty. I then take the bowl out of the water and measure the distances between the 3 marks. The distance from the bottom mark to the top mark should denote a volume of 237 ml. The distance from the bottom mark to the middle mark should indicate the volume of water whose weight equals that of the frisbee. After a little algebra, I decided that my frisbee weighs roughly 200 +/- 50 grams. I guess it may very well be labelled correctly.
