Ep 8. Under Pressure

Street Genius is a show where host and science enthusiast, Tim Shaw, takes everyday objects and shows how they can be used in extraordinary ways. In season 1 episode 8, titled "Under Pressure," Tim explores the power of air pressure and how it can be harnessed to complete seemingly impossible tasks.

The episode begins with Tim visiting a construction site to learn about the challenges associated with breaking through solid rock. He demonstrates how air pressure can be used to break up the rock into smaller pieces by using a pneumatic drill. He then meets with a group of engineers to learn about the science behind hydraulic systems and how they use air pressure to move heavy objects.

Next, Tim travels to a skate park where he meets a team of professional skateboarders who are looking to break the world record for the highest ollie. Tim uses his knowledge of air pressure to build a device that can help them reach their goal. He explains the science behind the device, including how the size of the piston can affect the amount of air pressure generated.

In another segment, Tim applies the principle of air pressure to the art of tattooing. He visits a tattoo artist who uses a machine that relies on air pressure to inject ink into the skin. Tim explains the mechanics of the machine, including how air pressure is used to create a vacuum that pulls the needle in and out of the skin.

The episode also features a segment on air-powered musical instruments. Tim meets with a group of musicians who use compressed air to create unique sounds. He learns about a variety of instruments, including an air guitar, an air drum kit, and an air-powered didgeridoo.

Throughout the episode, Tim highlights the importance of air pressure in our daily lives. He explains how air pressure is used in cars, airplanes, and even in our bodies. He also demonstrates how changes in air pressure can affect our perception of taste and smell.

In the final segment of the episode, Tim takes on the ultimate challenge of creating a hovercraft. He explains the science behind the device, including how the movement of air can lift and propel the craft. Tim works with a team of builders to construct the hovercraft, and then tests it out on a nearby lake.

As always, Street Genius is a fascinating and informative look at the science behind everyday objects. In "Under Pressure," Tim Shaw demonstrates how air pressure can be used to accomplish incredible feats, from breaking rocks to building hovercrafts. It's a must-watch for any science enthusiast or curious mind.
