" Francoise took the can of compressed air, used to clean the key board on the computer. She inverted her heated kistka over a piece of paper towel, placed the hose part to the tip and hit it with a blast of air. All of the contents of the kistka barrel came out on the paper towel. This would be something our ancestors would have loved to have on hand. I just did not want this fantastic tip to get lost. What a fantastic idea." N.B., Always read the label before using compressed air and follow the warning instructions.
