Several weeks ago while searching for science fair project ideas, we came across 
a suggestion to stack pennies and dimes placing strips of paper towels soaked in 
lemon juice in between the coins.  Supposedly when you wet your index finger and 
thumb and hold the stack, you will feel tingling.  We submitted the idea to the 
school for approval and it was accepted.  We tried the experiment yesterday 
evening and to our disappointment, it didn't work.  Now we don't know what to 
do. Do you have any suggestions of how we can make it work?  We have to turn in 
the project by Tuesday and the website we got the idea from is no longer 
available.  Thank you.
