Sensational Serpents

Today is Serpent Day, which celebrates snakes. Out of 3000 species of snakes, only 1/8th are venomous. The longest species, the reticulated python, can grow to over 30 feet long, while the tiny Barbados threadsnake, is like a 4-inch long spaghetti noodle. Snakes smell the air with their flickering tongues. Can you do that?
