This wonderful toy can be made in just a few minutes. You will need an empty matchbox, a matchstick, thread, a coin and some glue. Remove the drawer from the matchbox and make 4-cross holes in it with a long needle. Then apply glue to the base of the drawer and stick a coin to it. The coin will make the drawer heavy. Take a matchstick and taper both its ends and fix it across in the two holes along the width of the drawer. Weave a 1-meter long thread in the two holes along the length of the drawer. Tie loops on both ends of the thread. Stick a BLACK SPIDER on the backside of the matchbox drawer. 
The toy is ready to play. Hold the thread tight and the drawer up. As you loosen the thread a little the drawer slides down. On tightening the thread it brakes. 
When the thread is loose, the spider SLIDES; when the thread is tight the spider BRAKES. This is the principle behind this GO, NO-GO MATCHBOX.
