with mind-blowing
bubble experiments
You will need
- Five identical plastic bottles
- Water
Here's How:
Fill five plastic bottles with varying amounts of water. Arrange the bottles in order from most to least full. Blow across the top of each bottle and compare the different sounds.
Why?:
Changing the amounts of air and water in the bottles lets you change the pitch. When you blow, you are making the air inside vibrate. In bottles with more air, vibrations are slower, so
the pitch is lower.
First get permission to use kitchen equipment and eggs.
You will need:
- One raw egg
- Salt
Here's How: Take the raw egg and try to balance it on a hard surface.
Now, make a tiny mound of salt on a hard, smooth surface.
Very carefully balance the egg on top of the salt, then gently blow the excess salt away. With patience and a steady hand, you should succeed.
Note: Try this experiment without the salt on the spring equinox, or on the autumn equinox. During the equinoxes the sun appears directly overhead at the Equator, and the length of night and day are nearly equal worldwide. Carefully balance the egg on a hard smooth surface. If it doesn't balance, then try the experiment with some salt.
Why? Some people believe that the gravitational pull of the sun that occurs on the equinoxes can help keep an egg standing on its end. This idea is unproven, but it's interesting to test it. Another way to stand an egg up—on any day—is to use salt.
The salt crystals are almost perfect cubes, and they help form a pedestal that supports
the egg.
What you need:
- Small potato
- 2 bowls
- 2 tablespoons salt
- Knife
- Water
What to do:
Slice a small potato length-ways into several pieces that each have two flat sides. Place some of the pieces in one dish and the rest in another. Fill both dishes with water. Add two tablespoons of salt to one of the dishes, and label it "salt water." Let the potatoes soak for 15 minutes.
What happens and why?
Through an action called osmosis, water moves from areas of low salt concentrations to areas of high salt concentrations. Adding salt to the water creates a higher salt concentration in the dish than in the potato. Consequently, water in a potato that is soaking in salt water migrates out, leaving behind a limp spud!
People often make celery and strips of carrot go crisp by soaking them in fresh water. What happens if you soak these vegetables in salt water?
What you need:
- Bottle
- Soda water
- Three or four raisins
What to do:
Fill a glass or bottle half full with soda water. Drop three or four raisins into the water. Wait.
What happens and why?
Soda water contains dissolved carbon dioxide gas that collects on the irregular surfaces on the raisins. Once enough bubbles have collected, it will actually lift the raisins to the surface where the gas is released into the air, causing the raisins to sink once again.
What you need:
- Pen
- Card
- Tape
What to do:
Draw a picture of your favourite bird on a small index card. On another card the same size, draw a cage. Now tape the two cards, drawing sides out, on opposite sides of a pen. Spin the pen between your hands or fingers. Is your bird still free or did you catch it and put it in the cage?
What happens and why?
The bird appears to be caged. This is because of how your eyes and brain work. When you see the image of the bird, your brain holds onto the image for a short time--even though the image appears and disappears quickly. The same thing happens with the image of the cage. The two images actually overlap in your brain so the bird appears to be in the cage. The technical name for this effect is persistence. It is what lies behind every movie and every TV programme that you see.

I am passionate about Science and in particular spectacular demonstrations. In my daily teaching I use these to engage
pupils to thinking about big
ideas.
I love to share my passion and
enthusiasm for science with any
audience and above all to make the experience amazing, informative and
fun. Read more.
