Designed for demonstrating that vapor pressure increases when temperature increases. Apparatus consists of two glass bulbs which are connected with a glass tube and contain a colored, volatile liquid. Holding one of the bulbs in your hand causes the evaporation of a portion of the liquid, which forces the liquid into the other bulb. CAUTION: Only operate using hand heat.
