A better fly-swatter with science
Often in our Saigon, I get interesting ideas.
We were at a shop where the mom was trying to get the kid to swat the insects with an electric fly swatter such as this. But hard to interest angry-bird playing kids these days in such physical activities.
What if we add a counter to the swatter — the counter keeps a track of the number of insects killed. And build a leader board that ranks fly kills around the world.
