Pools and bathtubs are a great place to relax. But have you ever gone swimming in one while it’s rolling down the road? Duncan Forster and Phil Weicker took apart an old car, then built a hot tub that fit perfectly inside it. They filled it with water, and as you see here, they can drive it while bathing! They’ve nicknamed the car “Carpool Deville” and now just need a couple of bars of soap.
Wee ones: If your car had a tub in it, how many tubs would your home and car have together?
Little kids: If you’re adding 400 gallons of water to the pool car, how would you count that up by 100s? Bonus: If the car holds 2 people and 7 more rubber duckies than people, how many riders are there?
Big kids: If the highway speed limit is 60 miles per hour and the guys drive their tub just 1 mile per hour more slowly than that, how fast a record do they set? Bonus: The two men raised $10,000 for their project, and bought the old car for $800 on eBay. How much money did that leave them to rebuild the car? (Hint if needed: What would they have left if they’d bought the car for $1,000?)
Answers:
Wee ones: Different for everyone…figure out how many tubs you have in your house, and add 1!
Little kids: 100, 200, 300, 400. Bonus: 11 riders, since there are 9 (7+2) rubber duckies.
Big kids: 59 miles per hour. Bonus: $9,200.
