Ep 21. Super Sized Myths!

In season 5, episode 21 of Mythbusters, entitled "Super Sized Myths!," the team of Adam Savage, Jamie Hyneman, Grant Imahara, Tory Belleci and Kari Byron are investigating all things big and oversized. The episode features three separate myths, each involving something on a much larger scale than usual.

First up, the team takes on the myth that a person can be lifted off the ground using nothing but a bunch of helium balloons. They start by testing the idea on Jamie, tying him to a chair with a bunch of balloons attached. While Jamie doesn't seem to go anywhere, the team decides to try with a lot more balloons. They end up using over 5,000 balloons to try and lift Adam off the ground, with a final result that is both amusing and surprising.

Next, the Mythbusters tackle the idea that a person could actually skip across water like a stone. They figure out that they need a lot more velocity than a human can produce to get the right skim, so they start experimenting with various tools and vehicles that may work better. From jetski to homemade rig, the team tries out several variations before they find a winner, and then it comes down to testing it on the lake.

Finally, the team takes on the myth of the "big bad boom," and set out to examine how loud of a noise they could create using some of their favorite explosive materials. They start out with a small amount of Semtex, testing how far the sound can travel, before working their way up to a massive explosion that shakes the entire building. By the end, they've gathered enough data to see whether the myth holds any truth and what it could mean for those who live around an explosion at various distances.

Throughout the episode, the team brings their usual humor and energy to each experiment, making for an entertaining and informative viewing experience. They also take care to explain their thought processes and how they arrived at each conclusion along the way, allowing viewers to follow along with them and learn something new about science and mythbusting.
