Wellie Wanging is a game where you throw a rubber boot called a "wellington" as far as you can. You stand on one end of a field and then you toss the wellington boot and try to make it go as far as possible.
The goal is to throw it as far as you can without stepping over a line in the field. Whoever throws it furthest without crossing the line wins!
It might sound like a strange game, but people in some countries like to play it for fun at events and festivals. It's a bit like throwing a baseball or a soccer ball, but with a rubber boot instead.
The game can be played by people of all ages, but it's especially popular with kids who love to see how far they can throw the boot. So next time you go to a festival or fair, keep an eye out for Wellie Wanging and give it a try!
