"The whole Diet Coke and Mentos thing is long past its prime, but that doesn’t mean the powerful, fizzy reaction isn’t always going to be great fun to play with.

"These little LEGO cars are powered by the fizzy compressed gas which bursts through a nozzle and causes a spool of fishing line to spin. This, fishing line in turn pulls the LEGO cars along the ground at a high rate of speed.

"Top speed for cars pulled by their system – dubbed the “CoMet Machine” – is 40 km/h (~25 MPH). See it in action in the
