Pizza Cutter In Arm Illusion/Prank!

This 3D printable pizza cutter is designed to create a mind-blowing visual illusion, it looks like you’re slicing directly into your arm!

The secret? A cleverly designed missing section in the blade that aligns perfectly with your arm to create a convincing “cut-through” effect.

Even better…

When you slide it back and forth, it creates the illusion that it’s cutting deeper into your arm, guaranteed to make people do a double take!

I originally created this version of the in arm illusion years ago for a viral video that went on to get over 50 million views.
