Getting it to work just right was a real bugger. Someday I'll have to collect all the bits of the previous proof of concept models and photograph a progression of grenade concepts. Maybe start an AI museum corner of all of the adaptor and grenade prototypes. A pile of tortured airsoft guns and accessories we devoured in the development process too.

The first concept in the design line that ended up here was pretty funny. It used a length of tubing instead of a spiral passage in shell halves. When the grenade went off the pellets hosed out and tubing whipped around scattering a disc shaped pattern. It's successor had two tubes which had thermoformed ends to try to get them to point up and down so they blasted cones. I was goofy looking and turned into a snarl of hose but it proved the concept of a spinning grenade pretty well. I was going to call that grenade the TentacleNade.

There were many generations of timer builds too. The grenade in this first video featured a timer that had to be refilled with a small amount of water (around 10mL). It was consistent, but a little annoying to refill. I recently improved the design to not need water (which was pretty difficult), but I felt it made the product much better. V1 was going to have a water based timer, but I decided to jump right to V2 for this first release because of testing feedback.

I couldn't afford to rent the camera again to reshoot with the new delay, but the current build performs quite similarly to the earlier water delay build.
