Q & A

What materials are needed to create the magnetic toy described in the script?

You need a couple of ring magnets, a cardboard disc, a scale, a couple of sketch pens, and a straw.

How is the propeller for the magnetic toy constructed?

The propeller is made by cutting out eight blades from a card sheet, folding them along specified lines to stand at right angles.

What is the diameter of the card sheet used for the propeller?

The card sheet used for the propeller should have a diameter of about 10 centimeters.

How are the magnets arranged in the assembly of the toy?

Three magnets are placed on top of a plastic scale and three are placed below it, allowing them to stick to each other.

What happens when the assembled toy is placed under a ceiling fan?

The breeze from the ceiling fan causes the propeller to spin and the entire assembly to rotate around the magnets.

Can the toy be operated without a ceiling fan?

Yes, you can blow on the propeller with your mouth, and it will still rotate and spin around the magnets.

What is the purpose of the straw in the toy's assembly?

The straw serves as a base to press fit the fan on top, allowing it to rotate freely.

How many blades does the propeller have after assembly?

The propeller has a total of eight blades.

What is the significance of the blue and pink lines mentioned in the script?

The pink lines indicate where to cut, while the blue lines indicate where to fold the card sheet to create the propeller blades.

What aspect of the toy's motion is highlighted as intriguing in the script?

The script highlights the interesting and intriguing motion of the fan spinning and rotating around the magnets.
