I wanted this hovercraft so bad 35 years ago.
Do you remember this ad from BoysLife magazine?

Me and my dad made one. It worked.
Legends! 💪🏽
Ours was essentially a ply wood circle, heavy duty plastic attached like a big bubble and we cut a hold on the plywood, installed an electric leaf blower and put 2" holes spaced across the bottom of the plastic. It blew up when you turned on the blower and we took it to the indoor basketball court with a series of extension cords. It would glide right across the floor.
i saw something similar
Yep.
But also had a couple articles from popular mechanics that detailed building a hovercraft that I wanted to do more.
