Science rules!

Breaking The Ice


        Test Tube, labeled The Nerd, is a female contestant on Inanimate Insanity II. She is placed with The Bright Lights. She is voiced by Adam Katz.


As a proud, prospective, and self-proclaimed scientist, Test Tube devotes her life to the education of science. Since her debut in "Breaking The Ice", Test Tube has displayed an incredible amount of knowledge and intelligence in all areas of science and can be assumed as the most intelligent and creative contestant on Inanimate Insanity II. She talks with a strong vocabulary and enjoys making scientific calculations at random.

Along with her great intelligence, Test Tube is an impressive and masterful engineer. She was able to construct the rocket in "Marsh on Mars" within seconds and designed her own secret laboratory full of many inventions and gadgets in "Tri Your Best." However, Test Tube is quite possessive, unforthcoming, acquisitive, and secretive of her creations and harbors them away from the public.

Test Tube enjoys explaining scientific terms and facts, despite if other contestants didn't ask her to in the first place. Because of her constant science clamor, other contestants may find her irritating or annoying. Consequently, Test Tube may become socially awkward around many contestants who don't share the same interests. She can occasionally mutter to herself or make weird noises when in uncomfortable situations, and even confesses to her strange behavior in "Let 'Er R.I.P." after Fan does the same.

Occasionally, Test Tube can also be very foolish, dimwitted, nonsensical, and unintelligent. In "Theft and Battery", she foolishly tosses handfuls of rice on MePhone4 after he shuts down, not only doing the technique wrong but for the wrong reason as well. Test Tube has also proven to have a form of atychiphobia or the fear of being wrong. If Test Tube makes a miscalculation or is proven wrong, the result can cause her to undergo a massive amount of stress, enough to literally make her shatter.

Official Site Bio

Test Tube is a science fanatic and devotes her life to science and education. She is the most intelligent person in the game, but very bad at physical challenges. Her knowledge can come off as obnoxious and can irritate the people around her.

Test Tube… golly… we wonder where her passions lie! SPOILER ALERT: Science! Test Tube is a knowledge-driven scientist that has a slew of kooky inventions at her disposal. Her initial weakness, her social ability, has improved as a result of building friendships with some of the other contestants. Although she is generally understanding and kind, she becomes easily frazzled by the “unexplainable.” Over time, Test Tube questions if everything in life really needs to be explained. But as for right now, Test Tube strives to do what’s right… in the name of science! Science rules!!
