The childhood fascination of sitting, climbing, and even living among the trees has clearly not been laid to rest for some! It turns out that around the world there are many examples of modern, well-designed, and luxurious tree houses.

The houses range from simple, do-it-yourself constructions to sophisticated, expensive "tree mansions.&quot Some of them are the traditional block-like structures that we remember from our youth, while some take the form of a sphere. Several manufacturers specialize in these designs, including Baumraum, Free Spirit Spheres, and Lukasz Kos.

Rope ladder? Maybe. 360-degree panoramic view? Often! Sometimes, the intention of the tree house is to live in harmony with the environment. Sometimes, it’s a tradition that has been carried on within ethnic groups for centuries. And sometimes, it’s just for spunk.

But no matter the purpose, all of these creative houses are architecturally inspiring…and go to show that childhood fascinations can sometimes turn into economically viable adult pastimes!

Materials Needed: * A spool of insulated copper wire. Different gauges will produce different sounds, but you want something very thin. * Two Popsicle sticks. These can be new or used. * 8 neodymium magnets (2 for each string). These should be less then the width of the Popsicle stick. Again, different sizes will produce a different sound. You can see the rough size of what we used here. * Gorilla Glue
