Ballistic gelatin has been a test matter for us here at The Slingshot Channel for some time now. But there has been a lot of debate wether or not it REALLY simulates human flesh. Well, it simulates just a hunk of meat – like a nice piece of beef ready for the oven. What it lacks is bone, skin, and clothes.
Therefore, in this video a 10kg (22lb) block of gelatin has been “modded” – a piece of floor board simulates bone, and got deeply set into the gelatin. Leather from an old glove simulates skin, and a towel replaces more fancy clothes.
It works – a 25 mm steel ball, fired from an incredibly powerful winch operated slingshot crossbow, almosts lifts the entire block off the table – but can not penetrate the gel block through the towel and the leather.
A throwing knife, fired from a specifically designed slingshot crossbow at about 150 mph, easily goes through the towel, leather, gel and even through the floor board.
Even though the energy of the steel ball was no doubts higher than the energy of the knife, it was the pointy, sharp blade that made the difference – the pressure per square inch is a lot higher. A simple explanation based on the laws of physics.
The video also reveals a side effect of the “band catching” construction of the knife shooter – the shot is really, really silent, almost inaudible.
