60 SECOND SCIENCE CHALLENGE
DANCING CONVERSATION HEARTS!
WHAT YOU WILL NEED:
  • At least four conversation heart candies
  • A fresh bottle or can of colorless lemon-lime soda
  • A tall, clear glass

WHAT YOU DO:
Step 1: Fill the glass nearly to the top with the fresh soda.
Step 2: Take the four conversation heart candies and drop them, one at a time, into the soda.
Step 3: Watch the soda for a few seconds and observe the results...

WHAT'S GOING ON?
The conversation hearts are denser than soda so they fall to the bottom of the glass. But after a few moments, some of the candies slowly rise up through the soda. The carbon dioxide bubbles in the soda stick to the candies, and when enough bubbles accumulate on the candy, they lift up through the soda. Once the candies rise on top of the soda, the carbon dioxide bubbles escape into the air and cause the candy to sink again. As the candy sinks, more bubbles stick to it and causing it to rise again and repeat the cycle.
FUN FACT
Have you ever had butterflies in your stomach, sweaty palms and an increased heart rate while looking at someone you love? That feeling is caused by adrenaline, which is the same feeling you might get when you are nervous for any other reason, such as taking a big test!

STRAIGHT FROM THE SCIENTIST'S MOUTH
ANIMALS CAN AND DO FALL IN LOVE!

Here are 5 fun facts about different animals and how they court each other:
  • Puffer fish spend days creating beautiful, ornate circle patterns in the sand to attract mates. Males flap their fins as they swim along the seafloor to create spectacular patterns that can reach up to 2 m in diameter to impress their female suitors.

  • Male Gentoo penguins often present a gift of a stone to their mate in hopes of winning her over. Once paired, the male and female penguin will collect stones and plants to create a nest together.

  • Most seahorses are monogamous and some of them find life partners. When a male and female seahorse meet, they brighten in color and swim around holding each other’s tails.

  • Birds of paradise are quite the dancers! Male birds push their feathers up to form a skirt and perform a dance to catch a female's eye as they watch from above. It takes years to perfect the dance – young birds begin to learn how to do it before they develop adult plumage.

  • Bowerbirds construct fancy structures known as bowers for the female they’re courting. These are typically made out of twigs, bones, shells, flower petals and stones.
