This is one of my favourite cam toys.
It’s an ‘eco-ranger’ super hero. She flies through the air weaving up and down amongst the clouds. Her aim is to raise awareness about recycling and other ‘green’ issues.
One cam operates the eco-ranger and another moves the cloud.
Both cams are on the same axle which is turned by hand using a ‘crank handle’.
The two white paper tubes you can see are the ‘followers’ which rest on the cams and move up and down as the cams rotate.
