What combination creates a quantum soot in Little Alchemy 2?

In Little Alchemy 2, Quantum Soot is a hidden element that can be created through a specific combination. HereÔÇÖs how you can make it:

1. Create Soot:
- Combine Fire + House to create Soot.
(Alternatively, you can also create Soot by combining Fire + Tree or Fire + Forest.)

2. Create Quantum Physics:
- Combine Science + Atom to create Quantum Physics.
(To get Science, combine Human + Microscope or Human + Telescope. For Atom, combine Energy + Science.)

3. Combine Soot and Quantum Physics:
- Drag Soot onto Quantum Physics to create Quantum Soot.

Summary of Steps:
1. Fire + House = Soot
2. Science + Atom = Quantum Physics
3. Soot + Quantum Physics = Quantum Soot

This combination is part of the game's more advanced and hidden elements, so it might not be immediately obvious. Let me know if you need further clarification!
