1. Goodness Gracious
Great balls of Borax! Mix just 1 Tablespoon of Borax with warm water, cornstarch, glue, and food coloring for some approved bouncing off the walls. Your kids will love choosing their own colors. Find the recipe here.
2. Gak Attack
Have a glitter gak attack with this sparkly Borax recipe from Lil Luna. I can see this being great for some school projects.
3. How Ornamental!
I make these crystal ornaments every year with my students. There are always a few that don’t work the first time around, but otherwise, they are SO cool! Snowflakes and candy canes are the easiest to make, but you can also mold the pipe cleaners around cookie cutters to make other holiday shapes as well.
4. Egg-Shell-Ent Geodes
Make some egg-shell-ent geodes with Borax, egg shells, food coloring, and rock and sea salts. These geodes would make for a great science project, especially for 4th graders who learn about rocks as part of their Science curriculum. Get this and many other fun project ideas from Tinker Lab.
5. Flower Power
These crystal flowers would be a fun activity for a little girl’s party or sleepover. You’ll make them essentially the same way as the crystal ornaments. For more specifics, check out Pink Stripey Socks.
6. Just Glow With It
Here’s a glowing example of fun things you can make with Borax! Glow in the dark paint and neon food coloring are what makes this illuminated slime come to life. How excited would your kids be to make this around Halloween time?! Find out how here.
7. OffiSHELLY Fun Seashells
Make crystal seashells for an offiSHELLY fun summertime activity! You could also make these after learning about oceans or beach life. Source.
I remember the days of floam and silly putty back when I was in school. We all tried to sneak it into our tote trays and play with it during class. Some of us were more successful than others, but, regardless, we all loved playing with the stuff! Share the fun with your kids too. Get the DIY directions here.
