Welcome to On the Radar, where we preview upcoming events to mark your calendars for. In honor of National Ice Cream Month, Tampas Museum of Science & Industry is treating guests to free samples of Blue Bells newest flavor, Caramel Kettle Crunch — sweet and salty kettle corn, smooth ice cream and a swirl of caramel. Fear not, vanilla lovers, because they'll be serving that, too. In addition to the free doses of brain freeze, museum-goers get a chance to learn about the Science of Freezing as MOSIs InterActors demonstrate cryo freezing using liquid nitrogen (a word to the wise: don't stick your hand in it).
