Meet the Aquapod Bottle Launcher: an exciting toy for kids. You can use it to teach your young ones about the laws of motion. Just bring a bicycle pump, water, and a two-liter soda bottle, and you are set. Just fill the bottle halfway, put it over the Aquapod launcher, and pressurize the container using your bike pump. Aquapod does have a built-in safety valve to release pressure at 50 psi.
Aquapod Bottle Launcher looks like a lot of fun. But you don’t need me to tell you that adult supervision is required when kids are playing with a toy like this. You can get it for $35.
