The Capillarity Apparatus is intriguing demonstration of molecular attraction.
- Four Glass Tubes
- Metal Bass
- Length: 5½"
- Width: 4¾"
Adding colored water to the reservoir tubes of the apparatus shows how water ascends into spaces by capillary action. The water levels will vary in the four differently-sized glass tubes, rising above the reservoir level in the narrower tubes.
The glass unit is firmly supported in a metal base and measures 5½ x 4¾".
