What do you do with the old CDs at home, which aren't being used? How about involving your students to make some lovely toys out of it? We have curated some short videos on toys which can be made from old CDs.

CD Hovercraft

Discussion Points: Air Pressure, Newton's third Law

Blow and Float CD

This electric motor boat is easy to make and can be seen sailing in a bath tub or a small pond.

Materials Required:

two plastic bottle, two pencils (find used pen instead or bamboo stick of same size), hard cardboard (instead of popsicles), a small dc motor, propellor (you can make yourself with a plastic bottle), cello tape, soldering iron, glue (fevibond will work)

This Walking Cylinder is made from a toilet roll, straws and other odd materials.

Here are several versions of tumbling toys that are fun to play with and are easy to build.

You only need rubber band, bottle cups, a small plastic pipe (anything which looks like a small pipe), broomstick, glue, button (flad bead or washer) and make this simple toy which resembles a hoverboard. You can discuss elasticity, and the energy stored in a rubber band which when unwinds moves the toy. Also kids can learn about wheels and how they are fixed in moving objects like cars, bicyles etc.

Use a straw and some paper and make this awesome glider or you can also call it a straw plane.

By cutting the end of a straw you can create a reed instrument that you can actually play a tune on. You can also learn some things about the science of sound and music.

Also look at this video to make a reed based flute only with straws. Looks simple but you need to try this with your students.

Press fit a long plastic pen tube in a bottle lid. Press a hard straw on the rim for blowing. Stretch a torn balloon on the lid to make a taut membrane. Push the pen from below to touch the membrane. Now on blowing through the straw you will hear loud sound. The vibrating membrane will produce the sound.

Challenge your learners to retire their colour pencils and paint brushes for a day and ask them to express themselves only through their thumbs. Let the fun begin!
