  1. I doubt it if it is on the front page of YT, (or on YT at all). Since YT came out, it looks to be the results that our IQ as a society is dropping,---and I understand it is.

  2. Just from the title, I did not watch it: Back around 1970, when my older brother and I were elementary school kids, his real science class did a "drop egg" experiment. The kids got to use a shoe box to put the egg into, with any kind of "energy absorbing" packing they wanted. The boxes were then sealed shut and dropped from an airplane to the ground, (I don't know from what altitude). My brother used marsh mellows for packing material, and his egg survived the air drop, if I remember correctly. If not, he probably ate it for lunch. haha

  3. Another cause of error could be the back pack bag that the plunger is mounted in. It is not very rigid, so every time the plunger hit the switch, the bag moved a bit, changing distance and angle to lead to slight errors for repeatability. Just a possibility.

  4. Public school. That does not surprise me. If you try, you will learn so much more after you graduate.

  5. Amazing invention? Who invented it? I miss the days when inventors got the credit they earned. To say it was a community effort, (or made by communism), does not give the proper credit to the individual minds who invented,-------everything that was ever invented.
