"In space, no one can hear you scream." True or False? #

Adam and the MBJr's set out to test this famous tagline from the 1979 sci-fi classic — does sound transmit in the vacuum of space? With “vacuum” being the key here, the MBJr’s build a vacuum chamber that will be used throughout the episode.

With Adam’s guidance, they also build an analog “voice box”. They test sound results outside the chamber, but quickly realize that the device works by moving air, an interesting conundrum to be overcome in a vacuum. They then test the sound transmission in the vacuum chamber using microphones to record the results.

Can a fire extinguisher be used as a jetpack in space? #

Sandra Bullock made this maneuver famous in the movie when her character used a fire extinguisher to make a space jump from her capsule to a distant space station. Is this possible?

Adam and the MBJr's conduct a number of small scale experiments using CO cartridges in a vacuum chamber to observe results. Propulsion seems possible, but could you actually use a fire extinguisher to navigate between two points in the zero G vacuum of space?

They scale up the idea by constructing a hovercraft-type device to be used on an ice rink to achieve as frictionless a simulation as possible.

Try it out! 👩🏻‍🚀💨 Blast through the cosmos and avoid space junk to get to the escape pod! Can you make it in time before your fire extinguisher runs out?
