Introduction: How to Make Goop!

Picture of How to Make Goop!

It’s time to create a substance that would blow Einstein’s mind! Defying the laws of physics, this extraordinary goop is the easiest and most exciting experiment that children of all ages have enjoyed creating for many years. With just a few basic ingredients this creation can make any rainy or boring day come to life. Is it a liquid or is it a solid? I guess it’s time to find out…

Step 1: Collect Supplies

You will need:

  • 1 Bowl
  • 1 Spoon
  • Food Coloring of any color
  • 1 cup of Corn Starch
  • 1/3 cup of Water
  • 1 cup measuring cup
  • 1/3 cup measuring cup
  • 1 zip lock bag
  • Clean, flat working environment that can get a little messy
* Note: The brand of cornstarch and food coloring is not important to the end result.

Step 2: Measure Corn Starch

Measure 1 cup of Corn Starch loosely (don’t pack down) and pour it into your bowl.

Step 3: Add Water

Measure 1/3 cup of water and pour it into the same bowl as the Corn Starch.

Step 4: Add in Food Coloring

Squeeze three drops of color into your Corn Starch and water mixture.

Step 5: Mix Well

Now take your spoon and start to mix the corn starch, water and food coloring.

Note: The corn starch will make the consistency of your creation hard to mix but if you keep scraping the bottom of the bowl and stirring, until you can no longer see the color white of the starch then you are making progress.

Step 6: Time to Get Messy!

Make sure you are over a table where you don’t mind making a little mess, and grab a handful of goop with your hands and start to knead it between your palms.

Step 7: Store It!

To keep your goop in perfect condition it is time to store it in your sip lock bag. Use your spoon to scrape the sides of the mixing bowl and spoon it into the zip lock bag and secure the seal tightly.

Step 8: Clean Up!

Use a paper towel and a little bit of water to wipe down your working station. The starch will clean up very easily and it will be as if your experiment never happened!

Spelt is a grain, not a word. The word is spelled. I had to tell you.

1/3 cup of water didn't work for us. Ended up with clumps of colored cornstarch powder balls. Added 1/3 cup of more water, and presto - perfect!

Awesome messy project my son really enjoyed fun for our entire family actually thanks

We found the pictures valuable. We like that they are close up and there is very little distracting in the background. They were very specific, however several pictures were redundant. For example in step 2, there was a picture measuring the cornstarch followed by a picture of that cornstarch in the bowl. The second picture is unnecessary. This same idea relates to steps 2, 3 and 4.

Your gutters are too obvious. Using fewer pictures would still be successful.

We appreciate that your steps were broken up into smaller steps, instead of one large block of text. The instructions overall were very short and specific. We feel as though we could successfully make Goop.

Good job!

Good Lord Emily.dunn!!! I certainly hope people don't disect you the way you have scrutinized these instructions!!!! Quite certainly you wouldn't appreciate such harsh critiquing upon any of your endeavours!!!!

Thank you for a fabulous messy project to which my daughter enjoyed immensely!!!!!

idiotsare4real should we do this goop thing for school project.

This goop is very fun to play with. In the bowl it becomes a kind of a
solid seprated from the water and when you pick up the goop it turns
liquid.It is very fascinating to see the matter changes. And if you add a
Tbs of oil it will give it extra gloss and smoothness.

1. Pictures are sequential
2. Ingredients and Materials
3. Gave good background information
1. Unnecessary/Repetitive pictures and information
2. Last steps get wordy and have too much detail
3. Formatting issues with step’s title and overelaborating the
information that followed.

tmoses2382 (author)tmoses23822012-11-05

Overall, the instructions were highly repetitive which caused some confusion and made them hard to follow. The basic content and structure was present but a few more edits to remove the non-essential information would have improved the instructions.
