If you love playing catch (we’re pretty sure that your four legged friend does as well), then you might want to install some really powerful lights in your backyard to enjoy catch long after the sun has gone down. Of course, just in case you want to up the ante, why not exercise some form of DIY with this internally lighted LED ball? It will light up randomly as the ball is shaken up, looking as though you actually captured a fair number of fireflies inside as it flies through the air to the catcher. The entire process is pretty simple, and with some basic electronics knowledge, you shouldn’t have any problem cobbling this together over the weekend. A great time to bond with your kids too, we think. Relying on a 3V battery, this DIY project will use at least 15 LEDs inside.
