You can make a delightful Dump Truck with two matchboxes. You’ll also need 4 show buttons for the wheels, two needles, old ball pen refill, glue and a toothpick.
Heat the tip of a needle in a candle flame and poke it in the center of a show button. Slip in a 2-cm long ball pen refill which will act as a bush bearing. Then heat the other end of the needle and poke it in the pip of the other button. This way you will get a pair of good wheels which will spin smoothly. Make two such pairs of wheels.
Remove the drawer from the matchbox. Cut the side flap of the drawer and bend it down. Then glue it to the underside of the match shell. The drawer will become the LOADING PLATFORM of the dump truck. Now remove the drawer out from the second matchbox. Flatten the outer shell and cut off one-thirds. Stand the two-thirds shell in the drawer to make the DRIVER’S CABIN. Join both the matchboxes to complete the chassis of the DUMP TRUCK. Now make a hole in the driver’s cabin in place a toothpick lever as the LIFTING JACK. 
Finally tape the pair of wheels to the matchbox base. The truck is all ready to glide smoothly on the road. In the end load the truck with pebbles. Then press the toothpick lever with a refill. You will be surprised to see that the LOADING PLATFORM will slowly lift and all the cargo will be UNLOADED.
