🔬#MESExperiments 47: Ping Pong Ball Floats in a Water Vortex when inside a Vacuum Chamber https://youtu.be/6JJPi2JWKDo

In this experiment I have uploaded the 2018 video by The Action Lab showing a ping pong ball in a whirlpool or water vortex sinks under normal atmospheric pressure but floats inside a vacuum chamber.

Problems Plus 4: Plane Flying in Wind https://youtu.be/Up-l6Nt_w08

In this video I calculate the required direction for a plane to fly accounting for the wind velocity such that the ground velocity is due North.

🔬#MESExperiments 41: Homopolar Magnet Screw Motor https://youtu.be/qfrNG70uM2k

In this experiment I demonstrate a simple homopolar motor using just some tape, a 1.5-volt battery, a copper wire, a steel screw, and a magnet. 

🔬#MESExperiments 40: Replicating Viktor Schauberger's Rising Egg Experiment in REVERSE https://youtu.be/AZiKS8TZxfY

In this experiment I once again replicate Viktor Schauberger's rising experiment this time using a magnetic stirrer to show that a plastic egg falls 40% faster than a spherical ping pong ball.

🔬#MESExperiments 39: Replicating Viktor Schauberger's Rising Egg Experiment with a Drill https://youtu.be/GDrync4r82I

In this experiment I redo Viktor Schauberger's rising egg experiment but this time using an electric drill instead of manually stirring the water. This experiment confirms my earlier one, this time the plastic egg with the broad side up rose 21% faster and fell 24% slower than the ping pong ball.
