Around the U.S.

Intrigued by the National Math Festival, but unable to travel to Washington, D.C.? Play along in your hometown by visiting one of dozens of museums around the U.S.that will be offering Zometool Bubble Station demos on Saturday, May 4th!

Information about participating museums will be released in early 2019.

Explore Math at a Zometool Bubble Station

Zometool is a construction set that allow players to build beautiful and fascinating models from simple to profound. In fact, NASA has used Zometool for AIDS virus research in space and for a space station project! And the bubbles? Why, they’re soap bubbles, of course – but with a geometric twist.

Can you imagine using a bubble wand and dish soap to make a square bubble? How about a cubic, spiral, saddle-shaped, wormhole, or parabolic-shaped bubble? With the Zometool Bubble Stations, everyone from young kids to grown-up mathematicians will find delight in exploring how the principle of “minimal surfaces” makes possible not just the round soap bubbles we all know from our childhoods, but—with differently shaped Zometool “bubble frames”—geometric soap bubbles of many surprising forms.
