pop quiz - solution

Why, they're interactive, movable benches in Sihlcity, of course! So Dsole in Madrid and Elsa were both correct. But I think Lynn in Cheltenham takes the prize (perhaps a Frigor chocolate bar or two?) for the most creative response, especially because all of her suggestions could probably be applied. When people stand up, the benches pop right back up. So, if a really small person were to sit on the skinny end of the bench next to a larger person, and the larger one suddeny stood up, the small person could potentially be catapulted through the air, as Lynn suggested. You're also free to move the benches around the plaza at the mall entrance, and arrange them however you like--so you could turn it into a puzzle or team-building exercise if you really wanted to, which was another one of Lynn's guesses. Little kids can't get enough of these things--they keep knocking them down and then jumping out of the way when the benches bounce back up, simultaneously offering both exercise opportunities and self-defense training. The possiblities are endless...Apart from providing countless hours of people watching fun, can you think of any other uses for these 'benches'? There are also orange versions of these inside the mall.
