Legos.
For kids and parents to have a experience for building
Denmark
the thought of increasing kids building skills made him create legos
Legos are made of ABS plastic, and would pass through you undigested.
Probably balsa wood, LEGOs.
A key rack can be made out of Lego's by building a wall type structure with the legos. Then make a hook with the legos that sticks out and is sturdy enough and the right size for the keys.
Yes Legos can be built on the carpet but a hard surface is better to keep the Legos balanced and not tipping over when building another creation :p
you can get it at Toysrus however if you like Legos more you get halo Legos on a website called Brickforge
It is possible to buy sets of legos especially for the purpose of building a castle. The kit will provide all of the necessary pieces, and usually instructions for how to transform these into a castle. These can be purchased from Lego directly on their website, or through their stores. Alternatively, they can be purchased in many toy stores.
