Great vapor pressure demonstration! When the handboiler is held in your warm hand, liquid quickly travels from the bottom bulb to the top along with numerous bubbles, giving the appearance of boiling. These new and improved hand-boilers are from a thicker glass and less likely to break. Due to chance of breakage, they are not toys and are not recommended for young students. Sold individually and in cases of 12. About 16.5 cm (6.5") tall. Colors and styles may vary.
