Try to stand up while someone holds their finger on your forehead.
Hands together, feel fingers - yours should feel dead.
Close eyes while rubbing yours and other person's nose.
Find a partner, one to sit down on a chair with arms crossed, the other to lightly hold finger on the person who is sat down's forehead, then they try (and fail/struggle) to stand up. Then switch.
Hold hands up together, each to take it in turns to feel fingers - will experience a dead feeling.
Stand opposite each other, one person to hold their own and their partner's nose while eyes are closed and stroke the noses up and down, then switch. Should feel like their nose is far away from them or that their nose is growing.
