MICROWAVE SAFETY TEST WITH A MOBILE

Оглавление

Turn what you’ve learned on its head for a quick and easy safety test for your old microwave. You’ll want to run this check every day – if only to show off how clever you are.

You need a mobile phone, a microwave and another phone (landline will do fine). Check your mobile has a signal, place it in the oven, shut the door and call it up. You should find you go straight to answer machine, because the microwaves can’t reach the phone. If it rings it means the microwaves can get in and that means you’ve got problems, because if the waves can get in, they can get out as well. Watch out for your eyes. It stings when they start to cook.
