Why black clothes are warmer in the sunshine?

Do you want to know why you feel hotter when you are wearing a black T-shirt than a clearer one ?

Let's have a small experiment!

---

Ingredients:

• 2 glasses
• Water
• White and black paper
• thermoter
• scotch

Instructions:

Wrap a rectangle of paper around each glass and hold it with scotch or an elastic and pour the same quantity of water in them.

Put the both glasses into the sunshine and wait for an hour (or more).

Come back and measure the temperature of water in the two glasses.

Explanations :

Dark surfaces absord more light thant the clearer ones. That's why the water into the "black glass" is warmer. Light surfaces reflect more light.
