Show LIGHTING BY SUGAR The suggestion ha hai be been put forward forward forward for for- ward that there Is every very possibility that in the tile near future sugar Bugar will play an Important part art In the provision pro pro- 7 vision of a new method of artificial 1 lighting Experiments have shown that w when disks of loaf sugar are t placed on a lathe and rapidly rotated while a hammer plays lightly against them there Is an almost continuous radiation of artificial light At present present present pres pres- ent the practical value of or the discovery discovery discovery ery Is nil but It Is quite within the bounds of possibility that discoveries will soon be made that will render Its practical al application a certainty The cause of the phenomena Is not at pres present nt correctly understood under but It is probably due to some change In Inthe Inthe inthe the formation of the sugar crystals Cases where the act of or crystallization Is accompanied by flashes of ot light are not unknown and probably this Is duo due duoto duoto to some i similar cause At any rate Jt this appears to be he the Only feasible explanation as it has been proved that the light is not caused by the heating of or the sugar during the experiment ex ex- |
