We've been making crystals and geodes.
Our geodes are still in progress. This is what we did.
Materials
Epsom salts
2 cups warm water
eggshell halves
food colouring
- Spoon epsom salts into the warm water until no more will dissolve.
- Add food colouring to the solution.
- Pour this solution into the eggshell halves and leave the water to evaporate(This will take a few days).
- When the water has evaporated you have made your own geodes!
Mix two cups of water and one-half cup of washing soda in an old pot. Heat the water until it simmers, stirring to dissolve the soap. Pour this solution into a large drinking glass.
Cut a pipe cleaner into three pieces and twist them to form a star. Tie one end of a piece of thread to one leg of the star and the other end of the thread to the middle of a pencil or a second length of pipe cleaner. Make the distance between the pipe cleaner snowflake and the pencil such that when the snowflake is put in the glass the bottom is 1/2 inch above the bottom of the glass. Insert the pipe cleaner snowflake into the washing soda solution and set the glass in a cool location where it won't be disturbed for several hours to overnight.
