The Entropy Slayer 2000: Encapsulated Slingshot Crossbow with Heating System

admin — Mon, 23 Jan 2012 13:09:06 +0000

The scientific information we gathered using the thermal heat camera lead to more experiments: What happens if you heat a stretched band, one that already cooled down to room temperature?

It regains the power it lost during the cooldown phase. That is right, this video has the proof.

Now The Slingshot Channel has to use this critical information in order to build a slingshot crossbow that can heat the stretched rubber with the flick of a switch. The result looks bizarre and very uncenventional, but it does work very well.

Three heating films heat up the interior of an encapsulated band box. Using a strong 3300 mAh rechargeable battery, the bands can make the bands about 20 centigrade warmer than the environment, adding (or better, regaining) about 40% energy.

This weapon can be left cocked for a long time, and then – minutes before action is expected – be brought to top performance.

Two new slingshots are also presented as a bonus.

Do or Die: Zombie Hammer vs. Coconut

This is just a quick litlle video I made for all my fellow Zombie Hunters out there that wanted to see the impact of the Hammer on a coconut.

Note how little effort is needed to put the spike all the way into the nut. Go figure!

The “Alien Predator” Slingshot Experiment (Science!)

admin — Mon, 16 Jan 2012 01:28:33 +0000

This video uses a great piece of equipment for learning more about rubber bands: A thermal camera! This professional product made by Jenoptics has a resolution of 360×240, means, more than 86,000 laser thermoscopes are building an image. Much like the “heat visor” the predators use in the movies!

This way, heat structures can be made visible. It is mostly used to check how well a house is insulated, but it is also fantastic for scientific experiments.

Here, the thermal aspect of slingshot rubber is researched with the camera. It turns out that rubber bands store the muscle energy the shooter invests by drawing out into thermal energy – the bands warm up very quickly. When the shot falls, the bands retract and then they get very cold, intstantaneously.

The video clearly proves the fact that a long pause for aiming lowers the speed of the shot dramatically – because the drawn out bands loose heat, and therefore energy.

Last not least, a lead ball is fired three times against a rock – and it gets about 20 centrigrade warmer because of the deforming.

Roller equipped “Pickle Fork Shooter” variation and more

admin — Wed, 11 Jan 2012 00:50:49 +0000

Another week went by, and therefore there are new slingshots to be presented! See some variations on the “pickle shooter” concept, originally invented by dgui. Basically, a PFS is a slingshot that does not have any fork width. The fork arms are only present so you can attach the bands – the ball does not need any horizontal “clearance”, as it flies over the frame.

This is achieved by a slight twist of the pouch, and by flippibg down the hand while shooting. This is recorded in slow motion (1200 frames per second).

Also, some enhancements on the Zombie Hammer slingshots are shown, and a new “Panther” modification.

Last not least, one more reference to the online band manual, and the updated Thera Band Gold calculator. Here:
