How about a toy which encourages kids to eat a healthy variety of different things by rewarding them with a little fun?
Today’s invention is a trainset laid out on the dining table in a loop, as shown. Each of the dishes on the train corresponds to a diner and contains one component of a balanced meal. Each young diner wears a simple throatmike which registers when they are eating (and is tuned to ignore when they are talking).
Once everyone has munched, for between five and twenty seconds (as defined by a supervisory parent), the train moves to the next person and stops.
Hungry youngsters can encourage their less keen siblings to eat-up and thus provide themselves with a properly-paced, varied meal. (This idea first appeared here).
