STRAW WIRE MECANNO |  Malayalam

This is a very simple Mecanno where stiff plastic straws are used as building elements and wire is used to make joints. You will need wire with a loose sleeve on the top. Take a piece of wire and bend it five times and then cut it. Insert the wire in the last sleeve and make a three petal flower. You can make several joints and cut straws of equal lengths. 
Join two straws with a straight joint. You can bend it into an acute angle, right and obtuse angle. Join three straws and three joints to make an equilateral triangle. All the angles will be 60-degrees. With four straws make a regular square. Add one more straw to make a regular pentagon. 
Assemble 6 straws and 4, joints of three to make a Tetrahedron. Tetra means four, hedrons means made of triangles. So you will have a 3-D structure made of 4 triangles. Because triangles are strong so the Tetrahedron is a very-very strong structure. 
With 9 transparent straws and 6, joints of three you can assemble a Prism. Here the joints show very clearly. 
Similarly with a joint of four at the top you can make a Pyramid. Then make a Cube and place the Pyramid on top of the Cube to make a House.
