To demonstrate thermal expansion.
Ball and ring on handles with burner.
Description
When both ball and ring are at room temperature, the ball fits through the ring. If only the ball is heated, it expands so that it will not fit through the ring.

4A30.21 Ball and Ring
Thermal expansion
When the ball is heated with a blowtorch, the ball expands so much it no longer fits through the ring.
- [1] Ball on a stick
- [1] Ring on a stick
- [1] Blowtorch
- [1] Lighter
- [1] Metal ball holder
Important Notes
- Be careful with fire and hot items. Perform the experiment away from flammable objects.
- Make sure you shut off the gas completely when turning off the blowtorch.
- Show that it is easy to put the ball through the ring.
- Light the blowtorch and heat the ball evenly, waving the flame over all parts of the ball.
- Turn off the blowtorch.
- Show that the ball no longer fits through the ring.
- Place the ball on the metal holder so that the hot ball doesn't damage anything.

- Don't attempt this at home!
Last revised
- Putting the ring in dry ice also works, though it warms up rather quickly. If using dry ice, beware of its hazards, including frostbite, CO 2 poisoning, and embrittling of materials.

Ball and Ring
PIRA: 4A30.21
Most solids, like gases, expand when heated and contract when cooled. To demonstrate this, a metal ball, specially constructed so that it is just a little too small to fit through a similar metal loop, is cooled in liquid nitrogen and/or the hoop is heated on a propane stove. The ball will then easily fit through the loop, with lots of room to spare.

Ball and Hoop AKA: Thermal Expansion
A metal ball can pass through a metal hoop. When the ball is heated, it expands enough so it can no longer fit through.

Student resources, heating and cooling experiment.
This experiment will show how water reacts to extreme temperatures of hot and cold. The equipment you will need for this experiment include:
- A small empty beaker
- A bigger beaker with ice
- A flask with coloured liquid, the tube with markings on it
Method and observations:
- Place the flask with coloured liquid in the small empty beaker
- Pour the boiling water in the beaker and let it rest for a minute. You will see the level of liquid in the tube rising
- Now remove the flask from the beaker and place it in the beaker with ice
- Let it rest there and observe the level of the liquid in the tube falling as the liquid cools
In the ball and ring experiment, if the ball after heating is left to cool on the ring for some time, the ball again passes through the ring. Explain the reason.
On heating, the ball expands and increases in size and cannot pass the ring when left on it. as the ball cools, it contracts, size becomes less than the ring and passes the ring..
A metal ball which is passing through metal ring at room temperature will not pass after :
- cooling further
- the ball will pass in all conditions

This experiment is a volume expansion demonstration that shows that a ball is able to pass through a ring in a cold temperature but when the ball is heated using a Bunsen burner, the ball is unable to pass the ring. The equipment you will need for this experiment include: Beaker with water; Bunsen burner; Ball and ring apparatus Method and ...
The demo deals with the intuitive notion that the "hole" in the ring will get smaller as the ring is heated. Directions: Pass the ball through the ring while each is at room temperature. The ball may "stick" slightly as it passes through, but this reinforces the fact that it is a tight fit. Next, place the ball in the flame of the ...
This video is the practical demonstration of Thermal Expansion of solid in Practical Physics.----------------------------------------------------------------...
A metal ball passes through a snugly fitting ring when both are at the same temperature, illustrating the concept of thermal expansion. When the ring is heated, its diameter increases due to the expansion of the metal, allowing the ball to pass through easily. This experiment demonstrates the uniform expansion of solids when heated and is an example of the application of thermal expansion in ...

Ball and Ring. Description: A ball and ring are constructed so that at room temperature the ball passes through the ring easily. The ball is then heated for about 10 seconds in the flame from the propane torch, and the ball can no longer pass through the ring. Video clips of this experiment are available: .avi (Windows) and .mov (Mac).
In this experiment the ball will pass through the ring until the ball is heated in a flame and it expands enough to prevent it from passing through the ring. If the ring is then heated it expands enough to allow the ball to pass back through again. Pira DCS # 4A30.20

092. Tips. Two sizes of rings: SMALLER will allow the ball to pass through when ONLY when the RING IS HOT, the Larger RING (blue tape on the handle) will only allow the ball to pass through when the BALL IS COOL, the brass ball or rings are heated to change the result.

In experiments, the ball and ring experiment is a volume expansion demonstration experiment in which: (a) a cold (room temperature) brass ball is shown to be able to pass through tightly-fitted brass ring, (b) the ball is then heated with a flame, and (c) the experimenter then shows that the hot steel ball is unable to fit through the ring, as it previous was able to before, in the cold state ...
Normally the ball is able to pass through the ring. However when the ball is heated it is unable to pass through the ring, the reason being the ball expands on heating. When allowed to cool, the ... To demonstrate the expansion of gases, the experiment is set up as shown above. The round

Operation. This equipment consists of a handle with a hoop and a handle with a ball. At room temperature, the ball should easily fit through the hoop. If the ball is then held in a Bunsen flame for a minute or two, it cannot pass through the hoop. Through heating, the metal expands in the same way railway tracks can become longer and buckle ...

Galileo's idea for slowing down the motion was to have a ball roll down a ramp rather than to fall vertically. He argued that the speed gained in rolling down a ramp of given height didn't depend on the slope. His argument was based on an experiment with a pendulum and a nail, shown on page 171 of Two New Sciences.
