Glow in the Dark Eyeball Jet Balls (Pack of 6)

What you're getting

You get six bouncy balls shaped like eyeballs, complete with veins and pupils. Toss them around during the day, and they're perfectly decent fun. Come nightfall, though, they glow in the dark—which is where things get properly entertaining. Your kids will bounce them, throw them, catch them, and generally lose their minds over the glowing effect. Fair warning: they're designed to look a bit spooky, so if your lot are easily spooked, you might want to ease them in gently.
