��recently invented "break-away" bottles. For a long time artisans in the motion- picture industry have tried to devise a transparent "break-away" bottle, that is, a bottle which would have all the prop- erties of glass except that it would not cut or scratch. Until recently the bottles used were made of an opaque substance which would shatter readily, but which was not transparent. The problem has at last been solved in the modeling de- partment of the Balboa studio in Cali- fornia. William Dummer, chief of that department, has invented such a bottle. The material from which it is made, a combination of ether, gelatine, resin and oil, will crack and break like glass, but it will not cut and may be shattered over the head of the hero without in the least marring his manly beauty. And, what is equally important, it is transparent.

The descending bottle breaks into bits over the head of the hero, who drops in his tracks.

But, do not fear; the bottle was actually broken, but the hero remained unscathed. The Mexican's deadly This cup is made

���This Pocket Drinking-Cup Folds Up Like a Purse

AS a matter of sanitary precaution , every man, woman and child should carry an individual drinking cup. The health authorities have long recognized the importance of permanently banishing the unhygienic and disgusting public drinking cups and have strongly urged everyone to carry his own cup.

One of the difficul- ties in the way of carrying out this re- form was the lack of drinking cups that would fill the require- ments of hygiene and be so fashioned that they could easily be carried in the pocket. The cup shown in the picture consists of two aluminum plates, con- nected by a strip of oiled silk folded in bellows fashion. The edges of the aluminum plates are folded over the edge of aluminum and ^f the silk and crimp-

bc folded up flat ed tightly.
