This fantastic tool works by subjecting the weeds in your garden to very high temperatures (up to 1000C) which actively damages the cells of the plants. This is through a process whereby the water in the cells quickly boils, bursting them. This stops the transfer of nutrients and water in the plant, effectively killing it. After a few days the dead weeds can simply be brushed away with a weed brush or left to compost naturally. Each weed only needs a few seconds of exposure to the heat to be killed, making this process far more economical than traditional weed killers.
