The Green Apple Puzzle - a small aluminium apple (complete with stalk) which needs to be split into 2 halves. The apple has a horizontal seam across the middle and 4 dovetail joints each at 90° to each other. How is this possible. Something seems to rattle around inside. It comes with instructions but I refused to look at them - it took about 15 minutes of thought to work out how it should come apart, but when I tried it wouldn't budge. There is a second part to the puzzle which took me an extra 10 minutes to solve. There is a nice surprise inside!

It will reveal another picture with it open showing how 4 90° dovetails can be opened as well as what makes the rattling.
The ring is the object rattling inside - it has an interesting property. Depending on which direction you rotate it, it appears to spread apart or converge together.
When I find the solution to the cylinder I will post a picture of the contents here!!!!
