THE RISING RAISIN.

To perform this simple trick, all you need is a raisin and a glass of soda wa ,r. Take the pip out of the raisin and place it in the soda water. The pip will immediately sink to the bottom, and iu a short time the bubbles will gather round and bring it to the surface. The bubbles will burst, and the pip sinks to the bottom, only to be surrounded again by bubbles and brought to the surface. It will keep alternately rising and sinking while the soda water is still fizzy.
