What child doesn’t like science? Pair that with sticky, gooey and slimy fun and you may have a true winner for unplugged summer fun!

Mason Jar Science! Help kids capture the magic of science in a jar (and moms love the fact there’s less mess).  In this tabletop lab, kids learn the core principles of science by distilling experiments into a mason jar. Anything that encourages kids to step away from technology while awakening a love for scientific discovery is priceless.

From the kitchen counter to the classroom or science fair, Mason Jar Science will pique a child’s love for scientific exploration and uncover­ing the mysteries of the world — no lab coat required!

Something To Do | Let’s get SLIMY

Homemade Slime is all the rage with kids and there’s a side benefit for young ones with sensory issues too. notes that “for kids who seek sensory input, making and playing with slime can help with self-regulation. It’s also a good way to channel excess energy and excitement.”

So let’s manufacture some slime! Not to be confused with Goo (page 20), Slime (page 23) is very easy for kids to make and enjoy.

What you need:

  • Quart-sized Mason Jar with 2-piece lid.
  • 4 oz. white glue
  •  4 oz. Shaving Cream
  • 4 oz Contact Solution
  • 4 oz. Corn Starch
  • 1 tbsp baking soda
  • A few squirts of foam hand soap
  • 10 or so drops of food coloring

Add the white glue, shaving cream, foam soap, baking soda, cornstarch, and food coloring and mix with a stirrer. (for “runnier” slime, don’t put in the shaving cream, baking soda, and foaming hand soap). Add food coloring last. Have fun!
