Ep 4. Penny Drop, Deadly Microwaves, Radio Tooth Fillings

In season 1 episode 4 of Mythbusters, entitled "Penny Drop, Deadly Microwaves, Radio Tooth Fillings," the team tackles three different myths in their trademark hands-on approach.

First up is the penny drop myth, where the Mythbusters attempt to determine whether a penny dropped from the top of the Empire State Building could kill a pedestrian below. Using a high-powered air cannon and a life-size dummy, they simulate the fall and measure the damage done. Along the way, they also explore the physics of terminal velocity and the effects of air resistance on falling objects.

Next, the team turns their attention to the urban legend that microwaving certain materials can cause them to explosively combust. Using a variety of materials such as grapes, popcorn kernels, and even a CD, the Mythbusters test the limits of the microwave and try to find out if overheating can really lead to a dangerous explosion. Along the way, they also explore the science behind how microwaves work and what happens when they interact with different materials.

Finally, the team investigates the myth that radio waves from cell phones can interfere with tooth fillings, causing a painful shock to the mouth. Working with a group of volunteers and a variety of cell phones and dental instruments, the Mythbusters try to see if there's any truth to this pervasive rumor. Along the way, they also explore the basics of radio waves and how they travel through different materials.

As always, the Mythbusters use a combination of scientific method, creative problem-solving, and good old-fashioned trial and error to uncover the truth behind these myths. With explosive experiments and unexpected results, this episode is a thrilling addition to the series and a must-watch for science enthusiasts and skeptics alike.
