Eggshell Salt Geodes
Materials:
Epsom salt
Hot water
Food coloring
Eggshells
Begin by taking eggshells that have been broken at the middle and trimming them slightly with a pair of sharp scissors or a serrated knife to get a fairly even edge along the top.
Arrange your eggshells in an egg carton so that they have a place to sit upright when filled.
Make the salt solution by mixing Epsom salt into hot water until the water cannot hold any more salt. In other words, you will pour salt into the water (we used about a cup and a half of water, but you could easily get by with much less), mixing well with a whisk until you see that the salt is no longer able to dissolve into the water and a slurry begins to form. At this point, you can add a bit of food coloring as well.
Fill the eggshells with the salt solution. You can then set them aside to dry. This will take some number of days, depending on the humidity level in your house. As they dry, salt crystals will begin to form inside the shells, giving them an appearance similar to a geode. As an alternative, you can also put the eggshells into the refrigerator for a few hours and from what I hear, crystals will form this way as well. Nearly instant gratification! We haven't tried this method at our house yet, but I'm pretty sure that it is what Tiffany did with hers, and they seemed to have turned out well.

Supplies:
Black construction paper (or black cardstock)
Spray adhesive
White spray paint (optional)
Scissors
Directions:
1. Locate a clean spider's web (preferrably one in which the spider has vacated)
2. Spray the black paper with spray adhesive
3. Spray the spider's web from each angle with white spray paint, careful not to get any spray on nearby leaves, fence, etc. This may require the use of some newspaper as a dropcloth.
4. With the black paper behind the web, slowly bring the paper towards you until it touches the web. Then with the web on the paper, carefully cut the guy lines holding the web in place.
5. Document with chalk or pencil on the back of the paper the date and where the web was collected.
