No batteries? no problem

In this handheld electronic age I think we forget that there was a time when a handheld entertainment device didn't require batteries.  One example of these is the Waterful or Wonderful Waterful games.  These were made by various companies but the most notable were by TOMY.  These are the ones I remember.  They were great fun, until you lost the cap for the fill port and had to resort to duct tape to keep the water in.  I distinctly remember having the Basket Ball game while other friends had various other games.  These are the things that get my nostalgia juices flowing, how about you?  If you remember these post up your memories of the Waterful games you remember.

Here is a fun little video that should get those nostalgic juices flowing.

The one I had as a kid

I love Pac-Man, WHY did I not have this?
