  • Which one WOULD you let in your house or not let in your house? Cuz elephant would be preferred over the heals, right? Then if you said elephant then you're right! Right? Cuz the elephant distributes pressure seeing that it has a greater distribution. Right? So, was that just a mistake? Or am I confused? 3:53

  • You showed pressure with a tub of water vs a 2liter of water and the pressure looked the same. So If one goes into a large pool 10 feet below and feels the pressure in their ears, would one feel the same pressure if they went 10 feet deep into an area of water only 5x5 wide?

  • I would give this man any 5th grade class in the world. When you're learning, and having fun it's full on 5th grade. My 5th grade teacher had us building balsa wood gliders and para balloons.....we had sharp scissors, sharp knives, and created amazing things. I went through three years of math in the 5th grade because we were hands on with proven designs. We got to spend more time in the field than any other class in my school..... I got so lucky by being in that teacher's space.

  • You’re wrong about the elephant. You’re assuming all parts of the elephant’s foot distribute pressure evenly. But likely one or more points of the foot would hit first and be lower to the ground and what’s worse is there could also be a grain of dirt under the elephant’s foot that gets dragged around. The elephant would make a much bigger mess of the house.
