Math can be kind of like magic.
Back in 1858, a German mathematician named Möbius discovered a weird thing about a strip of paper. He could make it have only one side. It is called a Möbius strip in his honor.
Watch this video and make a Möbius strip. Or, make a special Möbius heart for Valentines Day! Mathematicians would argue that a Möbius heart is even better than candy! What do you think?
