How to catch a lion

1) Newton’s Method:
Let, the lion catch you. For every action there is a reaction, which is equal and opposite. It implies you catch a lion as a reaction.
2) Einstein Method :
Run in the direction opposite that of a lion. Due to higher relative velocity, the lion will also run faster and will get tired soon. Now you can trap it easily.
3) Schrödinger Methods:
At any given movement, there is positive probability for loin to be in the cave so set the trap, sit down and wait.

4) Inverse transformation Method :
We place a spherical cage in the forest and enter it. Perform an inverse transformation with respect to lion. Lion is in and we are out.

5) Thermodynamic procedure :
We construct a semi permeable membrane, which allows every thing to pass through it except lion, and then sweep the entire forest with it.
