Hand Boiler Love Meter Steve Spangler ScienceLove Meter
Are you hot enough to make the Love Meter boil? Simply grab the meter at the bottom and watch what happens. Is this really measuring your love or is it using your body heat?

The Love Meter is actually called a Hand Boiler. When the gas in the bottom bulb is heated with your hand, the increase in temperature creates an increase in air pressure. This increased pressure pushes the liquid up the tube to the top bulb. When all of the liquid transfers from the bottom bulb, air bubbles are forced up the tube, causing the liquid in the top bulb to appear to “boil.”

Color Changing Flowers
Carnations are the perfect flower to dye. Purchase white carnations then trim their stems. Place in water with a little food coloring and the colored water will travel through the flower and color the petals. You can do this easily yourself at home.

Hidden Messages – Friction Pens
FriXion Pens by Pilot are perfect to write secret, hidden messages to your loved ones. Write something with the pen on a piece of paper. The ink is erasable with the friction from the eraser. Friction creates heat. If you carefully place the paper above the flame on a candle (have an adult with you for safety), the heat from the burning candle will also make the ink erase. Give the blank piece of paper to your love and suggest they freeze it. When the ink is cold, it will reappear. Very cool!
