I put 2 little toy cars on the ground in the middle of the parking lot - just in front of the tire of my huge and heavy van! I slowly drive up to them - and over them! One of the toy cars is made out of plastic and is flattened and completely destroyed immediately - the other one is made of metal and lasts a little longer - but in the end it doesn't stand a change either and is ground to dust under the massive weight of the van!
