Hot water geyser, runs 5-10 min.
4C30.25 • C+70+70
Hot water geyser, cycles every 5-10 minutes. This is a working model of a geyser. The conical cavity is filled with water (1.6L) to about half way up the flared part. Place lit bunsen burner under the geyser and allow heating for 10 minutes. The geyser will recycle again in about 5 to 10 minutes. Flared pan catches the geyser water
