Vacuums are full of surprises! Did you know that they blow air out to suck things up? Or that old-fashioned vacuums were so huge, they had to be hauled from house to house by horses?!

Join Molly and co-host Baker as they learn all about these awesome appliances. They’ll dig into vacuum history, shrink to the size of air molecules and explore the inside of this curious contraption, and even check out a vacuum museum in Missouri. All that, plus a tricky new mystery sound that will blow you away!
