SeaMaiden...the plastic card trick is easy. To get the idea, try placing several fan leaves between two playing cards (about the size of my plastic taco when folded), place if flat on the table, then roll a pencil (like a rolling pen) along the top--moving from leaf tip to stem tip. Now, examine the sap that was squeezed out. All you need for the refractometer are a few good sized drops.
I use a 6 x 8 piece of clear plastic (old report cover) folded in half.
Sorry...this exercise will not do much to build your upper body...hehehehe.
