Before I start this post I want everyone this post is dedicated to Cordelia who gave an idea and that's how I made this post .Thank you.
Expirementing and Teaching isn't hard and that's what todays class is about unlike people who are shy Cordelia actually gave me this idea once again thank you.Okay today we will do a expirement and learn fom it.
Use a sheet of plywood at least 8 inches wider and longer than your planned volcano to make the base, to prevent the lava from staining surfaces during eruptions.
2
Step Two
Use salt dough, plaster or papier-mâché to form a mountain around an empty 2-liter bottle placed upright at the center of the plywood base. Be sure to leave the lid off.
3
Step Three
Form the model volcano's open top tightly around the mouth of the bottle.
4
Step Four
Make ridges and channels beginning at the volcano's top and ending at the base of the volcano for the lava to flow through.
5
Step Five
Let the volcano dry completely, then paint it with acrylics or spray paint. Plastic aquarium plants can be clipped and glued to the volcano for trees.
6
Step Six
Spray the volcano and plywood with a clear sealant after the paint has dried.
7
Step Seven
Mix 1 tbsp. liquid dish washing soap, 1 tbsp. baking soda and a few drops of red food coloring in a cup.
8
Step Eight
Pour the mixture carefully into the bottle.
9
Step Nine
Set the volcano in an open area, preferably outside.
10
Step Ten
Pour 1/4 c. white vinegar into the bottle and stand back to watch your volcano erupt!
Tips & Warnings
- Use wadded-up newspaper balls around the bottle to give the volcano its shape under a layer of plaster or papier-mâché paste, but make sure the surface layer of the volcano is solid, so that it can be sealed for re-use.
- If the lava is too thick, add 1 tbsp. water to the soap mix.
- To re-use the volcano, simply clean it off with a damp rag.
- Do not attempt to seal the bottle once the vinegar is added to the baking soda mixture--the resulting pressure could cause the bottle to explode.
