This is the beauty of mathematics that attracts everyone whether he/she knows mathematics or not.

[@alkeryn1700]

basically this is how you invert the sides of a sphere if you are allowed to self colide (ie make it go through itself).

[@uneaverageME]

@@alkeryn1700yup yup. It also technically doesn’t create any sharp folds which is why you can’t just take the top and drag it through the bottom till it flips.

Smoothly and continuously turn a sphere inside out without cutting or tearing it.

[@josemaderas7724]

Sharp bends sold separately.
