What you see here is the world’s largest rubber ducky, built by Dutch artist Florentijn Hofman. He’s made a whole bunch of giant ducks to float in big cities. Each duck has more than 200 pieces of PVC (a type of plastic), and a fan inside fills the duck with air to poof it out. Even so, the ducks weigh more than 2,000 pounds, and the biggest one stands more than 100 feet tall. If they could make noise, that would be one loud quack.

*Wee ones:* A rubber ducky for your tub might be about the size of your fist (your closed hand). Find 2 things in your room that are about that size.

*Little kids:* If the giant duck quacks, then splashes, then wiggles, then quacks, then splashes…what does it do next? *Bonus:* If one of these giant ducks shows up in Pittsburgh on a Sunday and floats away 4 days later, on what day does it leave?

*Big kids:* The second-tallest duck is 59 feet tall. How much taller is the 100-foot duck? *Bonus:* A 2-story house is about 30 feet tall. How many of those would you have to stack to stand taller than the 100-foot duck?
