What's so hilarious about it? D3O is a non-Newtonian fluid, and its properties change depending on the forces applied to it. Its application in racquets may or may not live up to the marketing hype, but there's no reason to discredit TennezSport for confirming that the material, itself, does what the manufacturer claims it does.
Mix up some corn starch and water (also known as "oobleck") like these fine folks have, and I think you'll be amazed at how non-Newtonian fluids can behave. Neat stuff!
