Who of us hasn’t lamented the fact that a late night trip to the beach for an evening swim can never include a beach ball for fear of it going missing in the dark? The folks at Swim Ways obviously have, because they stuck a motion-activated LED inside this inflatable Death Star beach ball so it’s visible all night long.
Since the LED and its tiny battery are perpetually trapped inside the beach ball to ensure they never get wet, it also means that when it dies, it’s dead for good. So to maximize battery life, the LED only turns on when the beach ball is being played with and bounced around. It’s also just ten bucks, so if you do have to replace it every summer, it’s not a giant financial burden. [Swim Ways via ThinkGeek via GeekAlerts]
