CrustaStun

This kitchen gadget is good for lobster lovers and humanitarians alike, though it's probably most appealing to those who are both. The CrustaStun is an electronic stunning device that kills knocks lobsters unconscious in a fraction of a second, then kills them with a jolt of electricity to their central nervous system. The entire process takes less than 5 seconds and sounds significantly more humane than slicing the crustacean in half with a large knife or simply plopping one into a vat of boiling water. Currently, it is only available in an industrial-looking restaurant model, but it could be worth the £1,500 to £2,000 if you eat a lot of lobster and want one for home use. A smaller, kitchen-sized one is being developed, which will probably have more aesthetic appeal.
