We’re loving this crazy sport called Bubble Soccer, shared by our fan Monica L. You have to watch the video to believe it: the players each wear a giant clear plastic bubble around themselves while kicking a ball. Since the bubbles are much bigger than the people, players crash into each other while running for the ball. No one gets hurt because when a player falls, he or she just bounces like a ball. You can buy or rent the bubbles online and at sports stores, so if you like playing soccer and knocking people over, this might be the sport for you.

*Wee ones:* A bubble is a sphere, or ball shape. See if you can spot 3 spheres in your room.

*Little kids:* If a bubble team has 10 players plus a goalie, like a real soccer team, how many players are on each team? *Bonus:* If 3 of those players are knocked down, how many are still standing?

*Big kids:* If a player crashes into another player every 3rd time he kicks the ball (starting with the 3rd), on which kick does he fall for the 7th time? *Bonus:* Will he fall on the 52nd kick?

Answers:

*Wee ones:* Items might include bouncy balls, balls from sports, or a ball of yarn.

*Little kids:* 11 players. *Bonus:* 8 players.

*Big kids:* On his 21st kick. *Bonus:* No, since 52 is not a multiple of 3. Quick trick to check: if the digits of a number add up to a multiple of 3, the number you started with is a multiple of 3, too. 5+2 = 7, which isn’t a multiple of 3, so 52 isn’t, either.
