Weather and science enthusiasts alike will love this stylish Galileo Thermometer and barometer combination! The enclosed glass balls will rise and fall with changes in the temperature while the level of the colored water in the tube at the side(you add food color of your choice; adult supervision required) will rise and fall with changes in the barometric pressure. This style uses liquid colored with dye in the balls; for the best color longevity it is recommended that you keep it out of direct sunlight. (HINT: The temperature will also measure more accurately outside of direct sunlight)
