InvisiBow

InvisiBows are inventions created by Test Tube that were stolen by Taco and Microphone in "Alternate Reality Show".

Appearance
InvisiBows, seen with two versions so far, look like regular bowties with a button in the middle, either circular shaped for the black version or diamond shaped for the white one.

Abilities
When worn and pressed, the InvisiBow allows the wearer to become completely invisible by turning bright green and fading out of view. If the button is pressed again or the wearer is harmed, the InvisiBow will cause them to reappear.

Trivia

 * The name "InvisiBow" is a wordplay of "invisible", as "bow" and "ble" sound alike.
 * In Mine Your Own Business, Microphone uses the white one and Taco uses the black one.
 * Along with the Time Machine Calculator, the InvisiBow is mentioned on Test Tube's character page on the Inanimate Insanity website.
