Father and son cut open a rattlesnake rattle – Watch video to find out what they saw!

New Delhi: Snakes are intriguing creatures. One of the most feared reptiles, they are super cautious and extremely dangerous and aggressive when threatened.

One of the most interesting species of the venomous serpents is the rattlesnake. Rattlesnakes are considered to be the newest and most evolved snakes in the world, as per scientists, owing to their sophisticated warning systems – the distinctive rattle as part of their tail.

As per Live Science, “Rattles are segments of keratin that fit loosely inside one another at the end of the snake’s tail,” explains Sara Viernum, a herpetologist based in Madison, Wisconsin. “These segments knock against each other to produce a buzzing sound when the snake holds its tail vertically and vibrates the rattle. Each time a rattlesnake sheds its skin it adds another segment to the rattle.”

Even though that explanation says it all, many have wondered what the rattle holds or its composition for it to make that kind of sound, but obviously, who in their right mind would approach a rattlesnake directly?

The curiosity bug eventually caught Dan and Lincoln – a father and son who started an insightful channel on YouTube, called “What's Inside?”, in which they cut up the most unimaginable things to find out what they hide. Their curiosity over such things is literally dangerous – not to forget contagious.

So, they bought a rattlesnake rattle on eBay (wise decision!) from a man living in Texas and decided to slice it in half to see what's inside.
