Activity

Make a Tornado in a Bottle

Source: Cool Science Experiments Headquarters

Purpose This experiment enables you to whirl liquid in the top of a bottle to create a vortex, as it drains into the bottom bottle. As the water flows down, air must flow up––creating a spiraling tornado!
Materials
  • Empty Glass Bottle with Lid
  • 3-4 tablespoons Glitter (the more glitter the better!)
  • Funnel
  • Water
How to
  1. Use the funnel to put 3-4 tablespoons of glitter in an empty glass jar.
  2. Next, fill the jar about 3/4 full of water.
  3. Put the lid back on the jar and make sure it is really tight.
  4. Turn the bottle upside down and quickly move the bottle in a circular motion for 10-15 seconds.
  5. Finally, set the bottle down on the table and observe the tornado that has formed

Build A Balloon Rocket Car

 

 

 

 

 

Source: Home Science Tools

Purpose A rocket is simply a chamber filled with pressurized gas. A small opening called a nozzle allows the air to escape, causing thrust that propels the rocket. You can demonstrate this when you blow up a balloon and let it go without tying it off. The balloon will fly through the air as all the air inside escapes.
Materials
  • 16-20 oz. plastic water bottle
  • Drinking straws
  • Wooden shish-kabob skewers
  • 4 plastic bottle caps
  • Balloon
  • Duct tape or masking tape
  • Nail, hammer, knife, scissors
How to Stretch out a large balloon by blowing it up and then letting the air out of it a few times. Next, make a nozzle. The size of the nozzle is very important. If it is too small, the air can’t escape with enough force to propel the car forward. If it is too big, the air will escape too fast and the car won’t go very far. Create the nozzle by taping four drinking straws together. Insert the straws into the mouth of the balloon and seal the opening by wrapping a strip of duct tape around it several times.

To mount the balloon/nozzle on the car, use a knife to cut two perpendicular slits (to make an X) in the top of the car about 4′ back from the mouth of the bottle, as shown in the illustration. Thread the nozzle through this opening and out through the mouth of the bottle. Leave about an inch of the nozzle sticking out of the mouth.

Find a hard surface, like a long table, linoleum floor, or sidewalk. Blow up the balloon through the straws at the mouth of the bottle. Pinch the base of the balloon to prevent the air from escaping too soon. Set the car down, let go of the balloon, and watch it go!

Egg in a Bottle

 

 

 

 

 

Source: Home Science Tools

Purpose The egg in the bottle experiment is a great way to learn about relation of temperature and air pressure.

Why does the egg slide into the bottle, even though no one is pushing it? The pressure of the air pushes it.

  • Before the burning paper was put into the bottle, the pressure of the air inside the bottle was the same as outside the bottle.
  • The burning paper, however, heats the air inside the bottle. This causes the air inside to expand. When the egg is placed on top of the bottle, it seals the bottle, and the fire eventually goes out.
  • When the fire goes out, the air inside the bottle cools. As it cools, the air contracts, and the pressure of the air inside the bottle becomes less than the pressure outside. Then, the higher outside pressure pushes the egg into the bottle.

Materials
  • Eggs
  • Saucepan and stove
  • Wide-mouth glass drink bottle (such as a Starbucks Frappuccino bottle – the mouth needs to be a little smaller than the egg. (We used a large egg with a Starbucks bottle, but with other bottles you might need smaller eggs. )
  • Vegetable oil
  • Matches
  • Strips of paper folded a couple times length-wise (slightly shorter than the bottle)

Activity

Making a Levitating Orb 

Purpose It is all about static charges. Similar static charges repel away from each other. When you rub the pipe in your hair you give the pipe a negative static charge. The orb is attracted to the pipe at first because the orb has a positive charge. As soon as the orb touches the pipe, it picks up a negative charge. Since the pipe is negative and the tinsel orb is now negative, they repel away from each other and the orb levitates! The orb will also take on more of a “ball” appearance when charged since all the tinsel strands are repelling away from each other. Did you notice the orb is attracted to other objects around you – including you? That is because most objects (including you) have a positive charge.

The Experiment

To make it a true experiment, you can try to answer these questions:

  1. Does the number of mylar strands affect how well the orb levitates?
  2. Do different materials (hair, fur, wool) build up better static charges?
  3. How long does the static charge last / how can you make it last longer?
  4. Do different widths of pipe affect the floating ability of the orb?
Materials
  • 1 inch (2.5 cm) wide PVC Pipe about 24 inches (60cm) long. You can also use a regular balloon if you do not have PVC pipe.
  • Mylar tinsel for Christmas trees. There are many types of tinsel and many will not work – you should look for the thinnest and narrowest possible. The tinsel used in the video is about 1 millimeter wide. If it is much wider than that, the orb may be too heavy to levitate. (You can order it HERE.)
  • A head of clean, dry hair OR fur or wool.
  • Scissors
