Speed Stroller

November 25, 2014

You might not remember being pushed around in a stroller when you were 1 year old. But even so, you’re probably pretty sure the stroller didn’t have a gas-fueled engine driving it at the speed of a car. A guy who likes to try to break world records decided to build the world’s fastest baby carriage – in 2006 he built the world’s biggest bonfire, but that wasn’t exciting enough. Colin Furze took a baby stroller, strapped on a motorcycle motor and a sports bottle filled with gasoline, and boom, that stroller drives as fast as 53 miles an hour! He also had to bolt a piece of metal to the bottom to keep the stroller heavy and low so it doesn’t go flying. Colin does have a baby son, Jake, but doesn’t let him or any other baby ride in this crazy vehicle. It’s fine for stuffed animals, though.

Wee ones: If a stroller has 3 wheels and a car has 4, which has more?

Little kids: If you put 3 teddy bears, 4 stuffed animal bunnies and a live puppy in the carriage, how many passengers are riding in there?  Bonus: Colin started building the stroller in 2012 when his son was born. How old is his son now? (We’re now in the year 2014.)

Big kids: If you can normally skateboard at 21 miles per hour, but with a motorcycle engine you can go double that speed, how fast is your skateboard now?  Bonus: If you wanted to reach the speed limit of 55 miles per hour, how much faster would your engine-powered skateboard have to be?

The sky’s the limit: If your 53 mile-per-hour stroller gets on the highway with cars driving 60 miles per hour, how much farther will those cars drive after 3 hours?




Wee ones: The car.

Little kids: 8 passengers.  Bonus: 2 years old.

Big kids: 42 miles per hour.  Bonus: 13 miles per hour faster.

The sky’s the limit: 21 miles ahead of you, since the cars will drive 7 more miles than you each hour.
