Toys for darkness

We use these to make our rockets visible for their entire flight at night launches, but you could easily come up with some cool ideas for your own use.

First up is Glow, Inc. This company sells glow-in-the-dark paints and powders, and theirs are the best I've ever seen. Not the pale and barely-visible luminescence we're used to, these are incredibly bright and last for hours. I bought the sampler powder pack, and have been playing with various application techniques. Very cool.

If you've ever seen the Indiglo watch faces, you know that they get very bright with the touch of a button. The folks at Night Launch offer sheets of this material up to 3" wide and 16" long in multiple colors. I got one of their starter kits for Christmas last year and believe me, this is neat stuff to play with.

Both sites offer plenty of great ideas on how to use their products, as well as occasional special offers and discounts. New products are also announced periodically.
