What a great tip! --> MAKE MASCARA LAST 3X LONGER!! A typical mascara dries out before half of it is used. When your favorite mascara starts getting dry, add 4-5 drops of saline solution or eyedrops to the bottle. Insert your wand and stir and TA-DA!! Fresh mascara! This can be repeated 2 or 3 times until all you mascara is gone.
