For people who genuinely feel that their home may come under attack, today’s invention offers some extra support.

It consists of a regular car airbag (cost: £200) which is placed under a foot scraper outside the front door.

Anyone who appears brandishing a weapon or acting aggressively can be blown off their feet by the homeowner remotely triggering the pyrotechnic element in the bag.

This would almost certainly be non-fatal but would be very disorienting for the would-be assailant. Several such devices could be buried under the gravel on a driveway and thus the need for gun ownership would be lessened.
