Small orange disc in tree, almost touched it

It happend when i was 10. Now I'm 30. It was on a sunny day in spring. I was playing in the garden while suddenly a thick fiber glass-like wire hang above my head. I called my sister, who was lying at the back of our garden sunbathing and asked if she had seen falling something. She saw the wire but didn't know where it suddenly came from. I followed the wire expecting a kite hanging in the tree, but it was on oval-shaped bright orange thing that was attached to it. I climbed into the tree until it was right before me. I wanted to grab it but it suddenly vanished without hearing or feeling something. I run confused to all our neigbours but they didn't know anything about it. Please contact me if you had a similar experience!
