Silly string is another fun invention that happened by mistake. The inventors had been trying to make a material that could squirt onto someone’s broken arm or leg and harden into a cast. But the soft string that you shoot out of a can works much better as a fun toy. The can squirts 20 to 30 feet of string at once, with 400 total feet of string per can – enough to make a very silly mess.

*Wee ones:* Which is *shorter*, a 6-foot squirt of silly string or an 8-foot squirt?

*Little kids:* If you order 12 cans of silly string and it comes with 1 free extra can, how many cans do you get? *Bonus:* If the can squirts 20 feet at once, how much longer is that string than you are? (You can round your height to the closest number of feet.)

*Big kids:* If the can holds 400 feet of string and you’ve squirted half of it, how many feet of string are left? *Bonus:* A baseball diamond is a square 90 feet on each edge. Can a 400-foot squirt of silly string wrap all the way around the bases once?

Answers:

*Wee ones:* The 6-foot squirt.

*Little kids:* 13 cans. *Bonus:* Different for everyone…subtract your height in feet from 20.

*Big kids:* 200 feet. *Bonus:* Yes, since the diamond is just 360 feet around!
