compare the safety of two outdoor heaters, an electric one for 2400 rubles and a gas one for 42, lena rubtsova, a tester of the miracle technology, and andrey sidorov, the chief engineer of the gas processing plant, went to one of the capital's parks. it immediately became obvious that the electric one has a major drawback, it requires. and you won't find a socket everywhere, we stocked up on a generator and first we'll check the fall sensors, both devices should turn off when tilted at 45°. it went out, it went out, you're just like a lady in a dance with it, you're pulsating, it turned on again, yes, everything is safe, but is it possible to get burned if you accidentally touch the heater? the role of the tester will be bell pepper with thin skin, we applied it to the grate of a gas appliance at different heights, we climbed under the cap of an electric one, but the barbecue failed, the skin remained intact, you can not be afraid of burns, well, what about the efficiency of heating, we will check whether the heat is distributed equally using a t-shirt that changes color when the temperature

lena rubtsova, a tester of the miracle technology, and andrey sidorov, the chief engineer of the gascessing plant, went to one of the capital's parks. it immediately became obvious that the electric one has a major drawback. it requires power, and you can't find a socket everywhere. we stocked up on a generator and will check it first.

our tester lena rubtsova and chemist oleg morozov are ready to check in the msu laboratory. bucket of cold water is at the ready just in case. the dream of a chemistry classroom, something is about to happen. let's begin. step by step to violate instructions. the solution was mixed, adding 10% more hardener. this mistake can be made if you do not weigh the liquid, only. control the volume with a measuring cup, at first it will heat up to 100 degrees, maybe then 120, and then how will the heat be removed, if we have a thin layer, then the heat is removed well, and if we have all this in such a thickness, it can boil right up to catch fire, neglecting the limit of one and a half cm, we make the layer fatter, the reaction will take about half an hour, so for now we move on to the next test. people use a burner to expel bubbles from the surface of the epoxy, this is not a completely safe moment, but you can do it, but very carefully and quickly, if you get carried away, the solution will catch fire, by the way, when the epoxy has hardened, it is no longer afraid of fire, many ar
