Toysmith 閃光軌道球

My niece absolutely lost it when I bounced this in the dark and it lit up midair. The flashing colors keep going while it rolls across the floor too, so she chases it around the whole living room.

Bought this for evening walks with my dog and the flashing lights make it so much easier to spot when it rolls into the grass. It bounces well too, and the lights keep going even after a few good throws.

My kids fight over this thing every evening, so I bought a second one. The lights are surprisingly bright and it survives bouncing off the driveway over and over. Great for keeping them busy after dark.
