Before You Watch This Video,

let me say a couple of things,

the slide is on a normal table and not stuck on a wall, the ball is not receiving any help from magnets, but the slide defies gravity neither the less, magic, or is it? it is so obvious once you watch the video, but it had me thinking for a few moments! all a matter of perspective, Struck Duck, who made this illusion, has an Etsy store where you can buy this and other illusions, or if you have a 3D printer, you can buy the STL files and make your own, as it happens,

there are a number of 'impossible' shapes you can down load for a 3D printer all for just £6.21, but remember, You will not receive a physical item with this purchase, if you would like to purchase the actual impossible sculptures, you can find many of them for sale in Struck Duck's shop, now where can I borrow a 3D printer?
