9) Following Shadows
• Avoids light and seeks shade
• Drives towards a shadow
• Stops in the shadow
• Tracks the shadow as it moves
Circuit: Shadow Follower / Braking Mode
Choose a place outdoor or underneath a light source,
which is placed at least one meter high. Your hand is the
best shadow. However, be careful not to wear clothes
with dark sleeves, otherwise varikabi would prefer to
follow the shadow of your arm.
When you hold your hand over varikabi, it stops. Then
slowly move your hand forwards or sideways so that
varikabi can follow it.
