Large Print Periodic Table

No time for fine print. This large print periodic table will help you with your eye strain.

Color Large Print Periodic Table

Color Large Print Periodic TableThis color periodic table contains the usual element numbers, symbols, element names, and atomic masses, but has the added bonus of larger type. This periodic table includes all 118 elements known as of 2017.

The element names are as large as I could consistently make them. I chose to make the names a uniform font size with the exception of the really long ones (rutherfordium, darmstadtium, roentgenium, and praseodymium). The rest of the information is much easier to read than the usual printable periodic table.

To print, download the PDF and choose either “Fit” or “Shrink oversized pages” under Page Sizing and Handling in the print options. Remember to choose Landscape for your orientation to use more space on the paper.

Cool Electroactive Slime That Reacts to Styrofoam

Electroactive slime is a opaque slime that reacts to static electricity. (Josh Hallett)

Electroactive slime is a opaque slime that reacts to static electricity. (Josh Hallett)

This recipe makes cool, non-toxic slime that appears to have a life of its own! It’s electroactive slime, so it reacts when it’s close to electrically charged objects. Rub a piece of polystyrene foam or a balloon on your hair or a wall to charge it and observe how the slime reacts.

Difficulty: Average

Time Required: 30 minutes

Electroactive Slime Materials

  • 3/4 c cornstarch (175 mL)
  • 2 c vegetable oil (475 mL)
  • glass or tumbler
  • refrigerator
  • 1x6x6 inch (25x150x150 mm) styrofoam

How To Make Electroactive Slime

  1. Mix the cornstarch and vegetable oil together in the glass.
  2. Refrigerate the slime mixture until it is chilled.
  3. Remove from the refrigerator and stir (separation is normal).
  4. Allow the mixture to warm enough so that it can flow.
  5. Take a block of styrofoam and charge it by rubbing it on hair, wool, or a cat.
  6. Tip the container of slime (which should flow slowly). Place the charged styrofoam about an inch (2 cm) from the flowing slime. It should stop flowing and seem to gel!
  7. If you wiggle the charged styrofoam the slime may follow or pieces of it may even break off.
  8. When the styrofoam is removed the slime will continue to flow.
  9. After use, refrigerate slime in a sealed container.

Here’s a variation of the recipe that shows how the slime reacts with static electricity. If she had refrigerated her slime, it would be more “slimy”. The slime has a life of its own whether it’s chilled or not:

Soap slime is an easy-to-make type of slime that is fun to play with and makes clean-up fun. Here’s how you make it.

Soap Slime Materials

  • leftover pieces from bars of soap (or you can use a whole bar)
  • water
  • jar

Make Soap Slime

You’ve probably made soap slime accidentally by allowing soap to get wet and stay wet in the bathtub or shower. Here’s how you make soap slime, on purpose:

  1. Place the soap pieces in a jar.
  2. Cover the soap with water.
  3. Let the jar sit for a day or two. You’ve got slime!

You can play with the slime or you can use it during bath time like you would ordinary soap. The soap slime with rinse away with water. Soap isn’t edible, so don’t eat this slime either. Also keep it out of your eyes. If you get some soap slime in your eyes, immediately rinse it out with water. Otherwise, have good clean fun!

Make Dish Soap Slime

Another cool type of soap slime to make uses dish soap. The ingredients for this slime are:

  • liquid dish soap (choose the color you want the slime to be)
  • glitter
  • clear non-toxic glue (PVA or polyvinyl alcohol school glue)
  • salt water or saline solution (although you’ll get better results using borax in water)
