He Blinded Me With Science

Spring not only brings tulips, longer days and sunshine - it also means the annual science fair at school.  For his project, John researched stalactites and grew one in our kitchen.  The results are pretty cool!


1. Heat water and stir in epsom salts until no more dissolves.



2,  Pour the solution in two jars on a cookie sheet.

 


3. Saturate a length of natural fiber yarn.  
Suspend the yarn between the two jars. 
Weigh the string down in the jars with paperclips.



Results after 2 hours


After 1 day


After 2 days


After 3 days
(The stalactite meets the bottom forming a column.)
