String Prints

I'm not sure where I saw the idea for this project.  I didn't pin it... shocking I know!

You will need:  a block for each person (square works best), string, paint and paper.

Cut a piece of string or yarn.  Wrap the string around the block, trying not to overlap it too many times.  (FYI, learn from my mistake, wrap it tight!)  Give each person one color of paint and a piece of paper

Dip the block into the paint string-side down.  (one of my boys learned that one the hard way). You may want to test out the print on a separate piece of paper to see if the strings are tight enough.

When you have it working they way you want, start in the top corner of the paper.  Each type you press you should then turn the block for the next one.  Of course you don't have to do that pattern, as you look at ours they are all different.  Let the kids experiement with arrangment, direction and placement.

Elephant Toothpaste

I love Pinterest, who doesn't?  I love that I can find fun things to do with the boys.  When I saw the pin for Elephant Toothpaste I knew I had to do it with them.  I checked out the blog post and thought, hey I have all that stuff at home.  Later I realized I didn't really, but it still worked, I'll get to that later.

You need an empty pastic bottle and a pan to catch the mess.

In a separate bowl put 2 Tbsp warm water and 1 tsp yeast.

In the water bottle put 1/2 cup Hydrogen peroxide.  The original post suggest using one that is 6%, but I used the one you buy at the grocery store that is only 3%.  Add to that 4-5 drops of food coloring and dish soap.  I used a funnel so that the boys could pour it in easier.

Now put the yeast mixture into the water bottle.  And watch it grow...

And grow...

The "toothpaste" in the original post was a lot fluffier, but that was caused by the stronger Hydrogen peroxide.  As you can see, the boys still had fun.  They decided to dump out the solution and try to drive and burry the cars in the foam.

 Oh and Preschool Powol Packets gives the scienctific reason for the reaction if you want to read that make sure you check it out too.
