There is nothing more fun than gooey, creepy, crawly science experiments for kids. Seeing their eyes light up when they get a reaction, or their faces crunch up when they touch something really gross, is priceless. Here are some fun ideas, and recipes, for your own spooky science activities.

1. Creepy density

Density experiments can be exciting for children. Seeing the different layers of liquids stay separate can be almost magical. Here are the ingredients, you'll also need a tall glass jar.

  • Treacle

  • Golden syrup

  • Water

  • Food coloring

  • Vegetable oil

Pour each liquid into the glass slowly starting with the treacle, then the golden syrup, followed by the water with added food coloring and finally the vegetable oil. Watch the different layers separate, and then try and float small objects, notice which layers the objects settle on.

2. The Blob!

No, not the black and white glob, from the old movie, that gobbles up unsuspecting women. This blob is made with a few simple ingredients. Begin by dissolving a teaspoon of Borax in one cup of water and set it aside. Next pour 4 oz. or 1/2 cup of Elmer's glue, the white school glue, into a medium mixing bowl and add 1/2 cup of water. Add a few colors of desired food coloring and mix. Then add the borax mixture into the bowl, stir for a few minutes then use your hands to knead until it starts to firm up and dry a little. Pour out the liquid left in the bowl, you can store the blob in a plastic Ziploc bag.

3. Oozing Pumpkin

This can be really fun, but is a little bit more involved. For this experiment you'll need a carved jack-o-lantern. You can get the 12 percent hydrogen peroxide you'll need from a beauty supply store. Dissolve the yeast in very warm water before you start, if it's too thick you can thin it out with some more water.

  • Add 1/4 cup of hydrogen peroxide (12 percent) to a small bowl.

  • Add a squirt of dish soap.

  • Mix in some food coloring, red for blood, green for slime.

  • Open up the top of your jack-o-lantern and carefully lower the cup of mixture into the jack-o-lantern. Don't tip it over or you'll have to start over from the beginning.

  • Now you're going to need to create your catalyst. Mix an entire package of dry yeast with 4 tablespoons of very warm water together. If the mixture is like a paste add a little more warm water to thin it out.

  • Pour the yeast solution into the cup and put the top on your jack-o-lantern quickly. It may take a little bit, but once the oozing starts, the result is well worth the wait.

4. Egg-citing

. Eggs are really amazing. In this experiment we'll make alien monster eyes, watch what happens when an egg is colored with markers and exposed to different environments, vinegar, water and corn syrup. Collect some raw eggs, color with sharpie markers to look like eyes and put them in a mason jar. Fill the jar with vinegar and watch for a small reaction. Let the eggs sit overnight in the refrigerator, and wash your hands. The next day rinse the eggs and observe the change they made overnight. Only the rubbery membrane should remain. Egg shells are made up of two elements called calcium and carbon, which are bonded together in calcium carbonate crystals. Vinegar is an acid, it breaks the crystals apart in a chemical reaction. The carbon and vinegar react to form carbon dioxide bubbles. Return the eggs to the empty jar and fill with corn syrup and green food coloring to create your slimy monster eyes.

5. Glowing goo

. Nothing entertains a toddler like slime, unless it's glow in the dark slime. This is a fun experiment for a child of any age. You might even find your husband enjoying this as well. Most of the ingredients in this experiment are in your home already, or easy to find. If you are concerned your children may ingest the goo, we suggest seeking out nontoxic glow in the dark paint. Here's what you need:

  • A big bowl

  • Corn flour

  • Water

  • Food coloring (optional)

  • Glow in the dark paint

Add a cup of corn flour to a bowl, slowly add the water, constantly mixing with a whisk or your hands until it becomes slimy, add the paint and food coloring if you'd like. If you hold the slime in a ball and squeeze what happens? What happens if you drop that ball on the table? Hold the goo up to a light then turn off the lights, how does it glow?

Science at home is a great way to have fun together while educating your children. Be sure to keep safety in mind and stay with your children while they learn about the world around them.
