Shells come in so many amazing shapes and sizes -  spirals, sand dollars, sundials, ones that whirl around, ones that twirl around, ones that twist to the side and some that even look like cookies! Our listener Lily had a great question about these shapes, and Mike Sanchez, a Naturalist at the New Mexico Museum of Natural History and Science, helps us get to the bottom of this twisted subject!

If you fold a sheet of paper just right, you can create a paper airplane that zooms through the air! But how do you make sure that your plane zooms across a room instead of nose-diving into the couch cushions? What makes a good paper airplane? We asked physics grad student Angie Huerta to help us find the answer.
