Science Playtime- Slime

Lately my daughter has been really into doing science experiments. I've found several great blogs that have kid-friendly crafts, experiments and playtime ideas. We recently made slime from the post I found at

This has to be one of the easiest projects we've done, as well as one of the most interesting.You start with these items:

1 cup water
1 tbs psyllium fiber (like Metamucil powder, only plain)
large microwave safe bowl
food coloring

Using a rather large microwave safe bowl, pour in the water and whisk in the fiber until mixed. Add 2-3 drops of food coloring and give it another little stir. Make sure to use a large bowl because the mix will bubble up significantly in the microwave.

We used this as an opportunity for measuring, pouring and stirring. Unlike baking, if we got the mix a little off, it wasn't going to turn out terribly. If you end up with a little more water than the recipe calls for, your slime will be more gooey. Using more fiber ends up with firmer texture slime.

Put the bowl in the microwave for about 5 minutes (maybe a bit more) and watch it bubble and grow. It forms a skin on top, so it shouldn't ooze over.

Remove the bowl from the microwave carefully, and make sure little hands don't get burned. You'll need to stir the slime with a wooden spoon until it cools off to the point that you can handle it.

After a couple minutes of stirring I was able to pull the slime out of the bowl and place it on the table. Stretching the slime helped it to cool further.

After the first blue batch, we had to make a second yellow one. They were fun to play with for the day. We put them in plastic storage bags overnight and they became stickier. Two days later they were pretty gooey and gross and needed to be tossed. Its possible that storing them in the fridge will lengthen the time you can play with them.

We will certainly be making the slime again! I'm considering adding a drop or two of scented oil next time to add another sensory dimension.

What is your favorite science activity?
