Quantum Gum is a gum in Bubble Gum Simulator. It can be obtained by purchasing the Infinite Size gamepass for 749 Icon-Robux. It has the highest capacity (infinite) of any gum.


  • This grants the user a sell button, allowing the user to instantly sell their bubble at any time.
  • If the player presses the sell button in any world that does not have a sell area, they will be teleported to the one in the Starter Area.
  • This is one of the only 6 gums that doesn't have the word "gum" on the decal, the others being Experiment 54, Experiment 32, Radioactive Gum, VIP Gum, and Alien Gum.
  • This is one of only two gums that can be purchased outside the Gum Stores. The other is VIP Gum. They are both packaged with gamepasses.
  • Technically, it isn't infinite. It goes up to Lua's number limit (which is 1.7 x 10^308, 17 followed by 308 zeros), then it'll convert into "inf".
