It is a foam or liquid and you spray it and it is soooo slippy even cars can not get traction.

Haha, and here I was about to say something like "Peter North".

MDS is an interesting and effective tool, but can be defeated easily. It is water soluble, so if it rains or someone breaks out the garden hose...

Agent orange

You can do something similar with bentonite powder. Depending on how thick you make would determine whether vehicles on pavement would have much problem. On grass, or much slope, wet bentonite is slick enough that you literally can not walk on it. A thin layer on a grass yard, wetted by a sprinkler when the time is right, and no one is going to walk up on you if they aren't wearing spikes of some type.

Just my opinion.
