Where There's Smoke ...

 

	. . . there's NO fire this time! Here's  another good trick with matches.
Strike them as carefully as you will, these matches will only produce smoke – But there’s lots of that!
Waterglass again!
Soak the head of safety matches in sodium silicate and let them dry for  several hours. Matches treated in this way will  splatter and smoke when  struck on the box.
