COOKING WITH COLD

RAY WAVE MIRACLES

DISCONNECTED BULBS LIGHT An electric light bulb lit without wires or socket, food cooked by invisible means, and the blood pressure of spec-j tutors raised to near danger-point—these were some of the "miracles of raywaves" demonstrated in the laboratory at Schneetady of the General Electric j Company. A New York correspondent writes: — "The mere presence in a room of an in-nocuous-looking vacuum tube, set down in a wooden cage and surrounded by a i network of wires, caused an incandescent bulb, taken from its cardboard box for the first time, to light to full brilliancy without wires or socket. A Neon tube was caused to flood the place with a red glow when merely j touched by a. spectator. j Then a naked and unattached copper bar, lying on the floor, became mysteriously alive. There was no change in its appearance, but a daring visitor, being warned and challenged to pick it up, did so, but dropped it again as if it were red-hot. He thought it was hot,' and his fingers were slightly blistered,. but the bar was as cold as ever. EGGS AND CAKES A wire was suspended over a table. To it was hung a glass tube containing a sausage. In a few minutes the sausage was done to a turn by induct-j ing currents received through space. ; Then eggs were fried ; little cakes were baked and water was brought toj the boil. I But most striking of all the short- j wave effects was when the end of a radiating aerial was touched with a. metal-tipped pole. immediately a greenish-white arc, representing thousands of volts, rose to the height of a foot or more. When the pole was removed the arc: remained like a plume of fire. Persons within the orb of the tube's activity experienced a feeling of warmth followed by pains in the limbs and joints. .Medical observations were made. Sev- ) eral men were placed near enough to •the radiating antennae to make measurerr.enl changes in bodily temperature possible. It was found that blood pressure rose so much within 15 minutes that the experimenters dared not allow the action to continue further.
