How to Build A Time Capsule: A True Test of Perseverance

Learn about NASA's Mars rover Perseverance while you learn how to build a time capsule.

Have you ever wanted to preserve time? Let us teach you how to build a time capsule! While you gather your materials and bulid your time capsule, check out this video about NASA's latest Mars rover, Perseverance.

On July 30, NASA is set to send its next rover to Mars. Our very own Science Interpreter Spencer served on a panel of judges that narrowed down the list of names. Then, the nation, and many of you, got to vote on its name!

The Perseverance rover will seek signs of ancient life and collect rock and soil samples for a possible return to Earth.  

Materials you will need:

  • Scissors  
  • Hot Glue 
  • Paper 
  • Pencil 
  • Cylinder that is opened on both ends 
How to build a time capsule

Directions:

STEP 1:

Take your hot glue gun and glue around the base of your cylinder. Once you have completed the ring, quickly place the cylinder onto one or the cardboard squares and wait for the glue to dry.  

Building a time capsule materials

STEP 2:

Take your scissors and cut the excess cardboard off of the cardboard square that was glued to the bottom of your cylinder.  

Assembling a time capsule

STEP 3:

Put the objects inside the time capsule that you have decided to preserve. We choose wooden tokens that represent the different exhibits and programs we put on here at the science center. You should choose something with meaning but nothing that you won’t miss for being gone for too long. 

add things to your time capsule

STEP 4:

With your piece of paper and pencil, write yourself a note. It is always fun to read a note that you wrote in the past. Make it about what you think life might be like when you open the time capsule and why you choose the items that you did.  

add a note to your time capsule

STEP 5:

Repeat steps 1 and 2 on the lid side of the cylinder to seal in the objects and the note inside the time capsule.

STEP 6:

Decorate! We choose to laser cut out some gears to glue all over our time capsule, but you can decorate your time capsule however you like. Make sure you leave some room for a warning label so nobody opens your time capsule too early.

STEP 7:

Once you finish decorating you should label your time capsule with a warning label so that way if anyone finds your time capsule they won’t open it too early.  

Lastly, decide where you are going to store your time capsule. You can keep your time capsule in many places, your closet, or even under your bed. If you bury your time capsule, make sure your time capsule can endure the elements!

How did your time capsule turn out? We'd love to see it! Submit photos or videos of your projects to the OSC Science Showcase for a chance to be featured!

DIY Blacklight: Use This Hack to Turn Any Smartphone Into a Blacklight

Share and decode secret messages with this DIY Blacklight hack!

Have you ever wanted to make something glow under a blacklight? Let us teach you one of our favorite hacks to make glowing highlighter messages and drawings at home with this DIY blacklight tutorial!

Recommended Age: 5+. Younger scientists will enjoy making and revealing their messages and drawings, but may need help putting together the DIY blacklight hack.

Materials you will need:

  • A phone with a camera light
  • Clear tape
  • A blue marker (a permanent marker, like a Sharpie, works best)
  • A purple marker (a permanent marker, like a Sharpie, works best)
  • White paper
  • A fluorescent highlighter (yellow works best)
Materials for DIY Blacklight

Directions:

STEP 1:

Rip off a small piece of tape (fold some of it over to make a tab for easy clean up later) and place the piece of tape over the camera light on the phone. Make sure you place the tape over the LIGHT, not the camera!

DIY Blacklight step 1

STEP 2:

With the blue marker, color the portion of tape over the light. You don’t need to color in the entire piece of tape; you just want to make sure the area directly over the light is colored.

DIY Blacklight step 2

STEP 3:

Place another piece of tape over the first. Color the area over the light blue again.

DIY Blacklight step 3

STEP 4:

Place one more piece of tape on top of the others. This time, color the area over the light purple.

DIY Blacklight step 5

STEP 5:

Draw a picture or message on white paper with your highlighter.

DIY Blacklight step 6

STEP 6:

Grap your picture and turn off the lights or go somewhere dark. Then turn on the camera light on your phone and shine the light onto your picture.

The Science Behind This Blacklight Hack:

Many highlighters fluoresce, or absorb then emit light, which makes them glow in the dark. But why?

  • Light is a spectrum. What we can see is called visible light. It ranges from red light to purple light. However, there are other types of light, including infrared and ultraviolet light (or UV) light. UV light is what a blacklight emits.
  • When you colored the tape with blue and purple markers, you created a filter that blocked out all colors of visible light except blue and purple. With the rest of the visible light spectrum blocked out, the resulting blue and purple light were enough to make the highlighter fluoresce because the wavelengths of purple and blue light are close enough to the UV spectrum, even though there is minimal UV light actually present.
  • Highlighters fluoresce under a normal blacklight because the ink absorbs ultraviolet light, which isn’t visible to the human eye, and remits it as visible light.
