Step One: Punch a quarter-inch hole in the cardboard. Cut and glue a piece of foil on the card to cover the hole. Do not get any glue over the hole. Gently poke the needle through the foil. Make the pinhole round and smooth; the more round the hole, the better your microscope will work.
Step Two: With the tip of a toothpick, carefully pread a thin layer of petroleum jelly just around the hole on both sides of the foil. Make sure to keep the hole open, free of jelly. With an eyedropper, squeeze a drop of clean distilled water into the pinhole. The petroleum jelly should hold the water in the pinhole. You may have to tap the card gently to get the water
in the hole.
Step Three: Point the flashlight upward. Place the object you want to study over the light. Look at the object through the water drop.
um i dont think it works it dosnt have the rite tecnolagy but i will try it becaes it looks cool

My class once made a microscope but it was slightly different.

I have a real microscope at home.It sees cells,but not much though.
i dont think it will work
it works because of water refraction!
i need to do that
It probibly dos’nt see cells just small detals.
You can just take a microscope slide and put a drop of tap water on it.
IT REALLY WORKS!!!!!!!
the scop was able to see cells
Of course it does!!!!!!!!!!!
Does it really work?
By using it can we see a cell?
this will be cool it will probly be expensive for distilled water though
it’s not that expensive its not even but 3 or 4 dollars for
a gallon at walmart
