Super Bubble Juice Recipe

This is the recipe I use when I need a gallon of really good bubble solution. It takes about 1 day to age, so if you need bubbles right away, just pour some detergent into some tap water. If you want really good bubbles, take the time to mix up this stuff.

Squishy Circuits

Making circuits with Play-doh is pretty cool. If you have some doh at home you can use that for conductive circuits. To take it to the next level you will need some insulating doh as well. Below are recipes for both at home conductive and insulating “Play-doh”.

Making Conductive Play-doh

The Ingredients

  • 1 cup Water
  • 1 1/2 cups Flour
  • 1/4 cup Salt
  • 3 Tbsp. Cream of Tartar (or 9Tbsp of lemon juice)
  • 1 Tbsp. Vegetable Oil
  • Food Coloring (optional)

Cooking Procedure

  1. Mix water, 1cup of flour, salt, cream of tartar, vegetable oil, and food coloring in a medium sized pot.
  2. Cook over medium heat and stir continuously.
  3. The mixture will begin to boil and start to get chunky.
  4. Keep stirring the mixture until it forms a ball in the center of the pot.
  5. Once a ball forms, place the ball on a lightly floured surface.
  6. The ball will be very hot. We suggest flattening it out and letting it cool for a couple minutes before handling.
  7. Slowly knead the remaining flour into the ball until you’ve reached a desired consistency.
  8. Store in an airtight container or plastic bag. While in the bag, water from the dough will create condensation. This is normal. Just knead the dough after removing it from the bag, and it will be as good as new. If stored properly, the dough should keep for several weeks.

Making Insulating Play-doh

The Ingredients

  • 1 1/2 cup Flour
  • 1/2 cup Sugar
  • 3 Tbsp. Vegetable Oil
  • 1/2 cup Deionized (or Distilled) Water

(You really want to use Distilled water to keep the amount of conductive ions to a minimum. Otherwise, the doh will be conductive rather than insulating.)

Cooking Procedure

  1. Mix solid ingredients and oil in a pot or large bowl, setting aside ½ cup flour to be used later.
  2. Mix with this mixture a small amount of deionized water (about 1 Tbsp.) and stir.
  3. Repeat this step until a majority water is absorbed by the mixture.
  4. Once your mixture is at this consistency, knead the mixture into one “lump”.
  5. Knead more water into the dough until it has a sticky, dough-like texture.
  6. Now, knead in flour to the dough, until a desired texture is reached.
  7. Store in an airtight container or plastic bag. While in the bag, water from the dough will create condensation. This is normal. Just knead the dough after removing it from the bag, and it will be as good as new. If stored properly, the dough should keep for several weeks.

The idea of creating electrical circuits using Play-doh and the recipes above come from The University of St. Thomas. Check out their Squishy Circuits page for more details.

How to make your own Naked Egg

[dropcap1]A[/dropcap1] “naked egg” is an egg that has no shell. Let me say that again, an egg with no shell. This is not something you normally run across and even when I show a naked egg to someone they often just don’t get the idea that the shell is gone – yet the egg stays intact.
