Share a hack for calming nerves

What can we use instead of clear school glue, glitter, or food coloring if those are hard to find?

If you can't find clear school glue, substitute clear hair gel or stir a teaspoon of glycerin into the warm tap water at the 'Squeeze clear school glue into the jar' step, swap fine glitter for larger craft sequins, and replace food coloring with a tiny piece of washable marker scraped into the water for color.

My jar is leaking or the glitter sinks too quickly — what should I try?

If the jar leaks after 'Turn the jar upside down over the towel,' tighten the lid and seal the seam with a ring of hot glue or waterproof tape, and if glitter settles too fast add a little more clear glue or a teaspoon of glycerin before screwing the lid on and shaking for ten seconds.

How can I make this calm down jar suitable for younger children or more challenging for older kids?

For toddlers have an adult pre-mix the glue, water, and glitter in a plastic bottle and replace fine glitter with larger, safe sequins before 'Screw the lid on,' while older kids can experiment with multiple food coloring drops, glitter types, or tiny waterproof charms to change how the swirl looks.

What are simple ways to personalize or improve the calm down jar after it's made?

To personalize the jar, glue glow-in-the-dark paint or small waterproof charms inside before tightening the lid, decorate the outside of the jar, and then share a photo or short note on DIY.org as suggested in the final step.
