Imagine a world where microwaving metal cans is not a recipe for disaster but a safe and sound possibility. Thanks to the innovators over at Daiwa Can, this dream might soon become reality with their latest invention, the Range de Can. At first glance, it may look like a simple plastic cap; in reality, it's a little piece of genius that attaches to the bottom of your can and promises to tame the fiery dance of microwaves.

The magic behind Range de Can lies in its unique design. It creates a buffer between the microwave and the can, reducing the risk of ionized air causing those dramatic sparks we all fear. Typically, when you microwave a can, especially near the bottom where the space is tight, free electrons in the metal can break free and ionize the air, leading to mini lightning storms. But with Range de Can, the chance of such sparks drops drastically—practically to zero, according to Daiwa Can’s testing.

However, before you rush to throw every can you own into the microwave, there are a few caveats. First, make sure to open the can. If you leave it closed, it might explode due to pressure buildup, creating an even bigger problem. Also, because metal reflects microwaves, your food might heat unevenly. The can itself might help distribute heat, but results can vary based on size and shape.

Moreover, not all microwaves and cans are alike. Some ovens' layouts or wattages might not work well with the Range de Can, and some cans may have linings that shouldn’t be microwaved. Always check the can’s materials before proceeding.

Currently, Range de Can seems ideal for cans of fish like mackerel, which are typically shallow and cooked inside the can during manufacturing, making them more suited for reheating. It's not quite ready for mass production, but stay tuned as more details are sure to emerge.

Until then, stick to cans designed for high temperatures and maybe steer clear of microwaving your Chef Boyardee—at least in Japan!
