"What's the best way to catch a falling child?"

Such as the toddler in China who fell 10 stories and survived, caught by a 31-year-old woman.

Physicists say the key to minimising injury to both child and catcher is to try and spread the energy of the impact over as much time as possible, perhaps by falling away while making the catch....

"If you fell as you caught the baby that might help as you are reducing the impact of the catch. You want to be able to fall safely, so grass and soil will give a little bit more than say concrete.

"The arms are going to take some of the force, so it would help if they were relaxed and loose."
