Cute idea. I will have baby food jars coming out my ears before i know it! :)Create a Snow Globe/ cute craft for an activity at a kids party if you add something from the craft store to the water it will make the glitter fall slower so it looks better. The stuff starts with a g I think.
Add Distilled Water and Glitter and a small amount of glycerine to slow down the fall of the glitter. Glue the plastic/ceramic figure/tree onto the slightly roughened [to give tooth] inside of the lid with epoxy [waterproof] glue. ~Allow to dry~ Invert and screw on [if lid is not seasonally coloured, firstly spray/paint it so] Turn upright, shake and grin :D
