Escape the Mansion Level 72 Walkthrough:
Drag the mirror to the left so it's above the pot and take the axe.
Pick up the white rocks and the torch.
Place the white rocks into the pot. Use the axe repeatedly on the crates until they break, then drag the wood to under the pot.
Use the torch on the wood and the steam will show the number 4185 on the mirror.
Enter the number 4185 at the top left.
Proceed to the next Escape the Mansion level!
