Do you like snow globes? I love them, and always have one sitting on my desk. When my mind goes in the idle state, then I tend to play with the globe. Shaking it vigorously, and watching the snow bits settle down bit by bit, has a calming effect.
Now, snow globes aren’t easy to find in India; and are often expensive. So I found an alternate version of it called the “glitter jar”. It’s super simple to make, with stuff that’s quite easily available at home and it is super fun!
Glitter Jar Recipe:
- Clear plastic jar
- A tiny toy (optional)
- Super glue
- Glitter powder
- Sealing tape
First open the bottle and stick the tiny toy to the inside base of the bottle lid. Next, fill 3/4 of the bottle with water. Sprinkle few pinches of glitter powder in the water, and then add 2-3 drops of glycerin. The toy should be stuck firmly by now, so close the lid of the bottle tightly. Shake the bottle to check if the glitter settles slowly. If not, then add a few more drops of glycerin and recheck the result. Once you’re happy with the flow of glitter, seal the lid with a tape; this is so that it does not open by mistake when kids play with it.
And then, enjoy hours of calming moments with your very own glitter jar!
I used glass jars when I did the activity with A & A; but one of the jar’s slipped from little A’s hands and broke the very next day. So I made new one’s with plastic bottles and they are still around the house.
If your children are older, then you could make this into a science activity. Have them fill the jar with water, sprinkle glitter, close the jar and shake it. Ask them to observe how the glitter settles in the water. The glitter will settle down quickly. Next, ask them to feel glycerin on their fingertips and describe it – is it light like water or does it feel thick or heavy? Ask them to pour a few drops in the glitter water, and then ask them to seal the jar and shake it and observe the effect.
Discuss why the glitter takes longer to settle when glycerin is put in the water.
