Mucilage Brush and Container Made of a Test Tube
An ordinary test tube, about ⁵⁄₈ by 6 in. in size, may be made into a mucilage container and brush that economizes the material and does not get the fingers sticky. The end of the tube is covered with a piece of soft cloth after the tube is filled, as shown in the sketch. A convenient way to care for the device is to keep it in a small tumbler.—A. H.
