Foam Fest 2015 continues! Heh.
Following up on the earlier experiments with foam pool noodles, I fiddled around with creating a glowing fairy mushroom. This rough proof of concept was banged out using the finest in dollar store materials- a pool noodle for the stem and a pool kickboard for the cap, both made of polyethylene foam. After trimming the parts to size they both received the slash-and-melt treatment before getting heat welded together.
The results of the lighting test were disappointing. I used the same 3 watt LED as in the earlier experiments. As before, the densely packed internal cells of the pool noodle did a fantastic job of transmitting light. Sadly, the very low density cells of the kickboard didn't share that ability. I think the basic concept is sound, but the facet density of the cap has to be high enough to bounce the light throughout the foam.
Moving forward, I need to find a source of high density polyethylene foam. Some industrial suppliers look to have what I need in 'shroom appropriate colors. This may seem like way too much effort for too little reward, but I think giant glowing mushrooms are insanely cool. More importantly, my nieces, wing-wearing fairy princesses all, share my view. There are few motivations more powerful than wanting to be the greatest uncle ever.
