# How do you make a water magnifier?

## How do you make a water magnifier?

What You Do:

1. Cut a dime-size hole in the middle of the cardboard.
2. Set the clear piece of plastic over the hole, and tape it down.
3. Dip the tip of the spoon in the water.
4. Set a piece of newspaper with printing, on the table.
5. Tell your child to carefully lift the magnifier and set it down on top of the paper.

### How does a water drop magnify?

The surface of a water drop curves outward to make a dome. This outward, or convex, curvature bends light rays inward. The result is an enlarged image on the retina of your eye. The object appears bigger than it is.

#### What happens if you make the water drop bigger or smaller?

The surface of a smaller drop is even more curved, bending the light rays even more inward. The result is a larger magnification: the object appears even larger. Changing the position of the water drop with respect to the letters and your eye will also affect how much larger the object appears.

Can you use a water bottle as a magnifying glass?

Homemade Magnifying Glass Step1: Draw a circle on the curved part of the bottle. Step 2: Cut out the circle. Step 3: Pour a little water into the plastic and hover it over a book or letter. The water plus the curved shape of the plastic make the words bigger.

How can you magnify without a magnifying glass?

Make a pinhole in a piece of paper or some other thin object, using a pin, safety pin, or the tip of a knife, and then hold it close to your eye and look through it. The image as viewed through the pinhole will not be magnified, but it will be in focus.

## How much does water magnify an object?

So, the approximate magnification is 1.33 in water. For objects which are closer up you would need to relax the small angle approximation as well as take the distance between the mask and your eyes into account.

### How much can a water droplet magnify?

You should find the water drop magnifies by a factor of 4 – 5. The smaller the droplet the more the magnification, but it is also harder to look through and focus. This was the principle behind the early microscopes, such as that used by the 17th century Dutch trader and scientist Anton van Leeuwenhoek (1632-1723).

#### Why does water work as a magnifying glass?

The reason water works as a lens is that light travels slower in water than in air. Therefore, it bends when it hits water just like it bends when it hits glass. If you somehow get water to take the appropriate lens-like shape, it can form images just like glass.

How do you make a water microscope at home?

WHAT YOU’LL DO

1. Step 1: Punch a quarter-inch hole in the cardboard. Cut and glue a piece of foil on the card to cover the hole.
2. Step 2: With the tip of a toothpick, carefully spread a thin layer of petroleum jelly just around the hole on both sides of the foil.
3. Step 3: Point the flashlight upward.

What can I use instead of magnifying glass?

If you have a smooth, cylindrical drinking glass made of clear glass, you could fill it with water and allow the convex shape of the glass to magnify the object behind it.
