Dana and Helen of Mombian blind you with science this week as they demonstrate a bunch of experiments and explorations for kids. Watch them use marshmallows, blue gooey stuff, really long words to describe peanut butter, and gummi bears like you’ve never seen them before (including one variation just for adults). They also point out the very lesbianish cartoon mom in a popular book of kids’ science projects. Whether you’re a parent or a cool aunt or godparent, you’ll want a few of these in your repertoire. Plus: An honor for Lesléa Newman, author of Heather Has Two Mommies, and a sneak appearance by Dana and Helen’s cat.
