Did any of you catch this on National Communist Radio on April fools day?? I am building one right away.

I think this could offer so much evil entertainment. I think you'd want to build a local static shield so your own cart would be misteriously protected.
Or is this an April fools its self. I have not logged in as I'm too busy with a project. But as soon as I can I have too as this is too impossible to resist. Be better if it could be selectively applied.

Ever noticed a painted yellow line in the parking lot around many supermarkets and retail stores? The magic yellow line emits a signal that causes carts to stop dead in their tracks, preventing carts from leaving the parking lot.
Now you can build your own portable yellow line-- with up to a 20 foot range. Need I say more? Hint: it works inside the store.
