Yesterday room 12 went to the science roadshow at Rotorua Intermediate. My favourite activity was the bed of nails, when I was lying on the bed of nails it felt like a massage on my back. The reason the nails don’t dagger into your back is because there's so many nails that it can hold you body weight & not hurt, that’s why if you touch a nail it’s sharp.
The nails pricked my skin as I lay on the bed of nails.It burnt like fire on my back.Filled with nerves the first time I did it , as soon as I did it my nerves eased . But the question is how come you can do it and it does not hurt? Because on nail will but a bunch won’t it spreads your weight.
