I think it's more glass dust than glass shards. Plus, safety goggles.

For those who want an explanation of the drop, I just recently learned this in class.

So what is happening is that when you drop the molten glass into the water it's cooling at an extremely rapid rate, so fast that the outside literally solidifies before the inside. When the inside does eventually cool below it's glass transition temperature it's attempting to contract an already solidified surface. This causes residual compressive stresses on the surface and tensile stresses on the inside. That's what makes the glass so strong, especially where it's thick (this is obviously due to Stress = P/A) because the stress applied, such as a hammer blow, has to first overcome the residual stresses, and then reach the stress at fracture.

However, it's obviously much easier to do this on a much smaller area, such as the tail. The explosion is because the moment the fracture occurs those residual stresses are released an actually aid the propagation of cracks throughout the entire structure. The same type of fracture can be replicated by causing glass to fracture under compression as opposed to tension, but that requires a stress 10x greater.

Headbutting might also mean that they just want to pet themselves.

So maybe none of your cats trust you.
