Genius!

Just in time for next Christmas, I've come up with ideas for a couple of educational toys. They're posted here in the hopes that a passing venture capitalist will see them and decide to finance my startup.

Yo-yo no-throw training device
Components: adjustable headband, elastic cord, safety goggles
How it works: Simply attach your toddler's favorite toy to the elastic cord and place the headband so that the cord connects at mid forehead. Now when your child throws her toy it will rebound and smack her on the head. Through the miracle of negative reenforcement, junior will learn that throwing things is bad.

Decibel shock training collar for tots
Components: collar with sound-sensitive toddler shocking device
How it works: The built in microphone measures the volume of your child's voice. If a pre-set volume is exceeded, a small shock is administered, humanely teaching your child to keep it down.
Note: In early testing, a slight problem with this toy has emerged. Here's a transcript from one of our tests:

Toddler A-37: Bwah bwah bway tway...Yay!
The last utterance exceeded the pre-set decibel limit and a shock was administered.
Toddler A-37: Ow!
The last utterance exceeded the pre-set decibel limit and a shock was administered.
Toddler A-37: Ow!
The last utterance exceeded the pre-set decibel limit and a shock was administered.

Our engineers are working to resolve this issue.
