I am perpetually 6 years old. Today at Target I purchased a “Sonic Search Submarine,” which runs on 2 AA batteries and zips around a swimming pool on a 20-second timer, emitting sonar “pings” every second until you hunt it down and press a button. If you don’t press it in time, it sounds an alarm and you lose. If you do, it disarms the detonation and you win. It’s completely fun.

I also got “Underwater Laser Light Fingers” which are red, blue, and green LED lights that you can fasten to your fingers, powered by a waterproof control box with a “flash” button (for quick illumination) and an on/off button that switches between fast blink, slow blink, steady on, and off modes. Again, completely fun, especially when paired with searching for the Sonic Search Submarine in a dark pool.

Yeah, I’m 6 years old.
