After putting together my minikit, I was thinking about how to waterproof a photon. I then remembered Bee using the gladwrap press n seal to pack his meds. So off to experiment.

I took a small photon-like led light and sealed it within the press and seal and dunked it in a bowl of water. About 20min later, i fished it out and could not detect any leakage and the light still worked fine.

Now i can waterproof the photon on my minikit....

Although i certainly won't go diving with it.....
