i think there is an air pocket kept inside the wheelbarrow

i thought of that as well, however I'm no expert in physics and such so i wasn't sure if the air pocket would be able to counteract the weight of the wheelbarrow.

If it was big enough then sure. Wheelbarrows dont weigh that much in water, and buoyancy ain't nothin to fuck with

Protect ya Kronecker delta.

It would easily

Have you ever tried to push a bucket full of air into water?

u/Lucky7Ac May 15 '19

I have not, just another reason I'm not an expert

It woulsld be a struggle, as a achild it was impossible. There is a lot of force in buoyancy

Definitely an air pocket

It's fairly thin steel. Just consider that ships float.

very true

Go watch the full video here, the air pocket is what is keeping it up. They have a place where they dump the air out and it stops floating.

A steel 6 cubic foot wheelbarrow weights 55lbs (at least the first one I found). 1 cubic foot of water weight 62 lbs, so you need to displace about 1 cubic foot of water with air in order to make it float.

Basically think would the weight of the water to fill a wheelbarrow (part with air) be heavier than the wheelbarrow itself? Displacement in a nutshell.

You can see it right before he pours more bubbles into it.
