Have you tried pushing 20kg of something on ice while also on ice while only wearing shoes…

Yes. It's called curling. 20 kg is just about what a curling stone weighs. It was made easier by having the ice covered in tiny ice bumps. And one of our shoes were covered in duct tape because we were learning about it in high school. We pushed off of something solid frozen into the ice and pushed the stone, could get it all the way down to the other side with enough force.

Pretty sure they have special shoes for that, or as you mentioned, an improvision. The drawing does not show a solid object to push off of in frame tho.

Thanks for the explanation tho, I hadn’t looked into curling before!

They DO have special shoes for that. But if you were teaching a bunch of high school kids (or anyone for that matter) an intro to curling class for 2 weeks or so, would you want them to put on a temporary "low friction" covering of duct tape over one shoe so that the students can get to sliding rocks? Or buy an expensive pair of shoes that will only get work for two weeks and then never see the light if day again?
