How to Build a Tin Can Planetarium

 

Do you live in a city where you rarely get to see the stars at night? Fear not! Because we’re going to show you how to make a tin can planetarium that’ll give you just as much to see, and a little bit more to do.

Are you familiar with the constellations? Perhaps you could use a little refresher from our friends over at Squidoo. Read: The First Five Constellations.

 

 

But reading about the constellations is not as fun as seeing the constellations, so here are 6 Easy Steps to Building a Tin Can Planetarium:

Supplies you’ll need:
• Empty tin can with the top removed (Be careful of sharp edges!)
• Sheet of paper
• Pen or pencil
• Scissors
• Hammer
• Tape
• Small nail
• Flashlight

Step #1: Place the can upright on a sheet of paper and trace around the bottom edge of the can.

Step #2: Trace the stars that make up your favourite constellation within the circle on the paper.

Step #3: Use the scissors to cut the circle out.

Step #4: Turn the can upside down and tape the circle to the bottom of the can.

Step #5: Use the hammer and nail to poke holes through the paper and right through the can at each star on your drawing.

Step #6: Place your flashlight inside the open end of the can. Turn it on and shine it on your tent or bedroom wall. There’s your constellation  – right before your eyes!
