Density’s Dancing Drops

Have you ever seen a Lava Lamp and wondered how it worked? It’s all thanks to density!

Some liquids are denser than other liquids, which means they are heavier or contain more “”stuff” per unit volume. A Lava Lamp is filled with liquid and a layer of colored wax on the bottom. The light at the base of the lamp heats the wax. Drops of liquid wax are less dense than the liquid in the lamp. So, as the wax softens to liquid, it floats to the top of the lamp. When the wax cools and becomes solid again, it floats back to the bottom.

You can create a similar illusion using a few items from the kitchen.


Density's Dancing Drops Supplies

  • A tall, clear glass
  • Water
  • Cooking oil
  • Salt


  1. Fill your glass two-thirds full with water.
  2. Density's Dancing Drops 1

  3. Add enough oil to form about an inch thick layer. Since oil isn’t as dense as water, it will float to the top.
  4. Density's Dancing Drops 2

  5. Add some salt.
  6. Density's Dancing Drops 3

  7. Watch drops of oil dance in the water as the denser salt sinks and carries drops of oil with it. When the water dissolves the salt, the oil floats back up to the top again, like a Lava Lamp.

Make an Exploding Rainbow

Water and oil don’t mix. Neither do milk and oil. Here’s a fun way to demonstrate that using a few items you probably have in your kitchen right now.


Exploding Rainbow Supplies

  • A pie pan
  • Whole Milk
  • Food coloring
  • Dishwashing soap


  1. Fill a pie pan nearly full with whole milk. Milk looks like a white liquid, but it’s really tiny drops of fat suspended in water.
  2. Exploding Rainbow 1

  3. Add three drops of each color of food coloring.
  4. Exploding Rainbow 2

  5. Add some dishwashing detergent. This will break the surface tension of the milk.
  6. Exploding Rainbow 3

  7. Watch the colors explode as the dishwashing detergent interacts with the watery liquid and the fat, creating currents that mix and swirl the colors. The show can last up to twenty minutes!

Make Your Own I Spy Bottle

“I spy with my little eye…”

Those words have been uttered countless times on road trips and in waiting rooms all over this land. Here’s a fun twist to that favorite boredom busting game your family may enjoy – an I Spy bottle! This is what you’ll need to get started.

I Spy Bottle Supplies


  • Empty plastic bottle, cleaned and dried
  • Rice (You could also use salt or sand.)
  • Funnel
  • Glue (I recommend a glue gun.)
  • 8-12 assorted small items (Our items included a marble, paper clip, safety pin, Barbie shoe, a broken green crayon, a bead, a jack, a ring, a rubber band, a sea shell, a penny and a button.)


  1. Use the funnel to fill the bottle 3/4 of the way full with rice.
  2. I Spy Bottle 1

  3. (Optional) Make a list of the items you’ve collected to add to the bottle. You can even photograph them! If you really want to get creative, come up with a rhyme. For example, “There’s a button, a bow and a penny, too. Can you name the item colored blue?”
  4. Add the small items you collected to the bottle.
  5. I Spy Bottle 2

  6. Glue the lid on. Since the bottle is filled with small items that could pose a choking hazard for young children, please do not skip this step. I recommend bringing out the big guns (i.e. a glue gun).
  7. I Spy Bottle 3

  8. Shake the bottle to hide the items.
  9. I Spy Bottle 4

  10. Start hunting!

The Pepper Experiment

Every mom knows about stuff that sticks – gum, candy, whatever that gunk was that you cleaned off the television screen. Here’s a fun (and not messy) way to demonstrate the sticking force between water molecules. This is what you’ll need:

Pepper Experiment Supplies


  • A large bowl
  • A small bowl
  • Pepper
  • Dish soap
  • Water


  1. Fill a large bowl a little more than half full of water.
  2. Pepper Experiment 1

  3. Add pepper. Lots and lots of pepper. The pepper will float because the water molecules are sticking together to create surface tension.
  4. Pepper Experiment 2

  5. Squirt a tiny bit of dish soap in a smaller bowl.
  6. Pepper Experiment 3

  7. Dip a finger in the dish soap.
  8. Pepper Experiment 4

  9. Touch the finger to the water.
  10. Pepper Experiment 5

  11. Watch the pepper scatter to the edges of the bowl.
  12. Pepper Experiment 6

Why did that happen? When you added the dish soap to the water, it weakened the surface tension. The water’s surface tension force is stronger than the detergent and water mixture’s force, so the water pulled away from the soap and took the pepper along for the ride!

  10. Cardboard Box Car 8

    Cardboard Box Car 9

  11. Thread a piece of ribbon through the slice in the front right corner and knot it on the inside. Thread the other end of the ribbon through the slice in the back right corner and knot it on the inside. Repeat with another piece of ribbon on the left side.

Make Your Own “Hourglass”

“Just a minute!”

How many times do our kids hear that? Here’s a way to help them visualize just how long that is: make an hourglass. Or in our case, a ten minute timepiece. Here’s what you’ll need to make it.

Hourglass Supplies


  • 2 empty plastic drink bottles, washed and dried
  • 1 plastic drink bottle cap
  • sand
  • funnel
  • duct tape
  • nail or other hole-poking tool


  1. Pour sand into one bottle using a funnel.
  2. Hourglass 1

  3. Use a nail or other tool to poke a hole in the plastic bottle cap.
  4. Hourglass 2

  5. Place the cap on the sand-filled bottle.
  6. Hourglass 3

  7. Invert the empty bottle, position it on top of the other bottle and secure them together with duct tape.
  8. Hourglass 4

  9. Flip the bottles over so the sand flows through.
  10. Hourglass 5

  11. You can use a clock to figure out how much time your “hourglass” measures and add or remove sand to adjust the time. (We used 8 oz. bottles and filled one 3/4 full of sand for a ten minute timepiece.)
  12. Hourglass 6

  13. Use your “hourglass” to keep time. We tried using ours in the morning to help us get out the door on time. It worked!

How will you use your “hourglass?”

Recycled Gift Wrap Wreath

The holiday season is filled with loads of parties and gift exchanges that generate enough gift wrap debris that, if you laid it out, could reach the North Pole. I’m making that up, of course. I’ve done no research to support that assertion. I have no idea how far that even is. But you get what I’m saying. We use a whole lot of gift wrap. And even the most enthusiastic present-opener can’t destroy it completely. So, don’t throw those gift wrap scraps away just yet. Gather them up and breathe a little Christmas spirit into their shredded remains with this recycled gift wrap wreath!

Here’s what you’ll need.

Recycled Gift Wrap Wreath Supplies


  • A paper plate
  • Scissors
  • Glue
  • Gift wrap scraps
  • Hole punch (optional)


  1. Cut the center out of a paper plate. (We traced around a round object to make a neat circle.)
  2. Recycled Gift Wrap Wreath 1

    Recycled Gift Wrap Wreath 2

  3. Cover the plate with glue.
  4. Recycled Gift Wrap Wreath 3

  5. Stick on your gift wrap scraps.
  6. Recycled Gift Wrap Wreath 4

  7. To hang the wreath, you can attach a loop of ribbon. We used the hole punch to make a hole and looped a piece of string from a gift bag handle.
  8. Recycled Gift Wrap Wreath 5

  9. Deck your halls!
