Impossible Slide Illusion

A cool perspective illusion where a ball will roll the up the slide.

Features:

• A very quick and easy print.
• Only uses 30g of filament.
• Interesting conversation piece.
• Ball included.

Usage:

• The illusion only works from 1 specific angle.
• It works best through the perspective of a camera or when closing one eye.
• Place the slide in the correct position and drop a ball at any point of the slide.
• The ball wil appear to roll up the slide!

Extra Info:

The included print profile is set to 200% scale so if you're downloading the STL you may want to scale it up at a bit.

The included ball is printed in 2 halves and needs to be glue together post print. This is ensure that it rolls smoothly as printing one that's whole will not roll correctly.

Thanks for looking!
