Such simple items can be transformed into a cool activity that blends both science and art. If you have an empty water bottle, water, vegetable oil and food coloring, you can make this fascinating kid's activity! As a bonus, it also teaches kids about liquid density (and an explanation about that is included in this post!).
Materials 1 cup sand 1/2 tbsp cornstarch 1 tsp dish soap water (as needed) Optional* Food coloring Directions Step 1: In a bowl, mix fine sand and cornstarch together. Step 2: Add dish soap and water, and combine thoroughly until well mixed. Step 3: Add food coloring if you’d like! Step 4: Let dry for 1-2 hours. Step 5: Start playing!
Water Cycle Craft - no instructions, but pretty easy to figure out what to do and mostly straight-cutting except for the sun which is pretty easy to make or find elsewhere. These would be fun to make for the WOW journey.
