Here’s how to make yours.

Materials:

• 2 x pieces of white card
• A pin or sewing needle
  
  

Step One:

In the centre of one piece of card, punch a pinhole using your pin or sewing needle. Try not to make the hole too large, and keep it as clean as possible. This card will act as your projector, and the other card will be the screen.

Step Two:

Go outside to a sunny area where there are no trees or buildings obstructing the Sun. Stand with your back to the Sun with your shadow directly in front of you.

Step Three:

Take the piece of card with the pinhole in one hand and hold it above your shoulder. You should be able to see the full shape of the card in your shadow.

Step Four:

In your other hand, take the other piece of card and hold it out in front of you, and in front of the projector card. The shadows of the cards should overlap.

The card with the pinhole will project an inverted image of the sun onto the screen, and in full sun it will project a full circle.

To make the image appear brighter, bring the screen card closer to the pinhole card. To make the image appear larger, move the screen farther away.

Step Five:

Witness the eclipse! The image of the Sun on your card will turn into a crescent shape as the Moon creates a shadow.
