In a recent episode, the two are on a quest to discover the insides of a rattlesnake’s vigorously rattling tail. Mr. Markham purchased a rattlesnake tail from an eBay seller in Texas for the experiment.

The two visited the Phoenix Zoo in Arizona to compare the purchased rattlesnake tail to that of a living rattlesnake. The species is venomous, just like many other serpents slithering across the world.

When returning home to dissect, Markham noted that rattlesnakes can rattle their tail 50 times per second for hours on end. Little Lincoln attempted to do so as fast as the snake but failed.

Using a razor, Markham cut into the snake’s tail. It crackled popped and almost didn’t break open, forcing him to use some muscles to make the experiment work.

Inside was two hollow layers of hardened keratin at the end of the tail which bounce against the other for an alarming sound that warns predators to stay away.
