A bike-powered backyard rollercoaster

Best part about this video is the kid is wearing a mask outside alone with his dad.

Is the mask necessary though? He couldn't be more socially distanced as it is in that ride. Alone. Outside. Ffs 🙄

He’s so lucky to have a dad like this, or to even have one at all

the kid's wearing a mask. he's outdoors. there's no one else around. 🙄

"While you may feel overwhelmed by undertaking this seemingly complex task, building roller coasters actually isn’t all that complicated." 😬

What happens when the kid gets bored of the ride?

Still wearing masks in Asia I see.

Spectacular "toy" for his son 😂

Thats genius

Pretty coool....but why's the kid wearing a mask outdoors?
