You can build the monster car simply by putting the pins inside the cylinders and the support holes, then you can insert the four supports into the base.

After you have inserted the four pistons, with the tops on the cylinders, turn the tops onto the cylinders; put a bit of glue (we recommend Super Attack) between the top hooks of the cylinders to hold them and wait five minutes.

Now you can insert the springs around the piston-cylinders assembly and then you can put the basis2 pins inside the heads of the pistons.

Block the car with the two hookes on the basis and insert the wheels into the tyres; after in the basis pins.

Now you have your monster car. Yeeeha!
