Subspace Tripmine is a gear that was published in the Marketplace by Roblox on June 19, 2009. It is an item from Roblox. Tripmines are dangerous. Once 2 seconds have passed while the mine is idle, it will turn invisible. Touching an invisible tripmine prompts it to become opaque again and soon afterwards create a powerful explosion. Any parts within the 16-stud explosion radius of the mine, including the ones of players, will be colored pink. Sometimes tripmines are sentient, like this one.
