These plastic balls light up and make “boingy” noises when they are bounced. Great fun.
Each ball is 2 inches in diameter and is made of a medium-density rubbery plastic. The holes you see in the balls actually go all the way through, possibly to help carry light to the outside and make them sparkle. It’s hard to picture the difference when they are lit; in one picture the blue one seems to have a glare. However in real life they light up brightly and flash, which made it pretty much impossible to get a picture when they were all lit together. While they are lit, they make a loud cartoon spring sound. Hitting or bouncing them on a hard surface makes them light up. The balls come in three colors: red, white and blue.
The center of each ball contains the mechanics and whatever battery is inside. They rattle a little bit when you shake them. . If you are concerned about environmental disposal, they would need to be treated as a battery.
These are great fun, just because the result is rather unexpected, even when you know its coming.
They are probably not suitable for pets unless supervised. I suspect a dog would make quick work of chewing the ball apart. A cat might have more trouble. They are probably safe for kids, unless of course the kids try to cut them open on purpose!
They are hard enough that they would be best for outdoor play for kids. It would be pretty easy to start breaking things in the house.
They make interesting party favors or promotional gifts. I have no idea how long the battery will last. But for the price they deliver a whole lot of fun for $2.00
