These mobiles capture the wind and create a perfect illusion : the ball seems to move upwards or downwards but in fact stays in the same place.

Simply add your choice of colour in the comment field.
A few tips :
Keep the nylon string as long as possible.
Turn the mobile every time you walk past, the mouvement will last from 5 to 10 minutes. Visitors will be unable to resist having a go.
