I have a spiral glitter wand in a holder on my desk, filled with glycerin and multi-colored glitter. When I turn it upside down, the glitter slowly drops to the bottom, making beautiful shapes as it does. Sometimes the glitter gets stuck and I have to shake it up to get the air bubble to the right place so it can rise again, freeing the glitter to fall. I feel like that myself sometimes too. My glitter gets stuck and I have to shake it up to get it flowing again.
