The best party balloons are the ones that float. So a crazy guy named Daniel Boria wondered if HE could fly using party balloons. He tied 110 balloons to a folding chair and flew right into the sky — really! But the wind blew him the wrong way, and he landed in a field. What goes up must come down!

*Wee ones:* If Daniel blew up red, blue, yellow, green, and white balloons, how many colors is that?

*Little kids:* If Daniel took off at 2:00 pm and crash-landed 2 hours later, when did he land? *Bonus:* If Daniel really needed just 100 balloons, not 110, how many extra balloons did he blow up?

*Big kids:* In the 1980s, a guy nicknamed Lawn Chair Larry tried this trick with 45 GIANT balloons. How many more balloons did Daniel use? *Bonus:* If Daniel spent $1 for every pack of 10 balloons to make 110, plus $20 on the chair, how much did his flying machine cost?

*The sky’s the limit — for real:* If 1/2 of the 110 balloons had popped after 10 minutes, and then 1/5 of the ones *left* had popped 1 minute later, and then 1/2 of the ones left after that had popped, how many balloons would have been left?

Answers:*Wee ones:* 5 colors.

*Little kids:* At 4:00 pm. *Bonus:* 10 extra balloons.

*Big kids:* 65 more balloons. *Bonus:* $31, since the 110 balloons cost $11.

*The sky’s the limit:* 22 balloons left. If 1/2 the balloons popped, he’d lose 55, leaving him with 55. If 1/5 of those popped he’d lose another 11, leaving him 44. Then if 1/2 of those popped, he’d lose 22 of them and have 22 left.
