Handleiding

DID YOU KNOW?

Our skin is the human body’s largest organ. And it’s a lot more than just a simple

covering for our body. There are lots of sensory cells in the skin that are responsive

to different stimuli. There are touch sensors — as you know from your tickle

experiment — that are sensitive to light

contact or pressure. Then there are pain

sensors, which warn you about

possible injury. And there are

temperature sensors, which send

signals about heat or cold. When you’re

hot, you start to sweat. The sweat

evaporates on your skin and cools you

off in the process. If you’re cold, you get

goose bumps: All the little hairs on

your skin stand up straight and form an

extra layer of air around your body,

which helps to warm you up.

WHAT’S HAPPENING

Have your assistant tickle you. Where does it

tickle the most? Are there places where it

doesn’t tickle at all? Then switch places.

The first player to make the other one

laugh is the winner!

Bonus Experiment:

Try tickling yourself with the feather! Doesn’t work? The

reason lies in your brain: It knows what you’re planning,

warns you, and the feather’s touch doesn’t come as a

surprise. You adjust to it beforehand, so you’re not ticklish.

Feel It!
