This document describes an experiment called the "Magic Water" experiment. It involves placing a mesh over the opening of a jar, filling the jar with water, and inverting the jar without spilling. The mesh allows toothpicks to be passed through the water surface without breaking tension. The experiment demonstrates principles of atmospheric pressure, surface tension, and buoyancy. A quiz is included to test comprehension.

MAGIC WATER EXPERIMENT BY TRINITY ROBINS
MATERIALS JAR LID TO JAR WITH MIDDLE CUT OUT WATER MESH OR GAUZE TOOTHPICKS CONTAINERIN CASE OF SPILLAGE CARD
WHAT TO DO 1. PUT MESH ON JAR AND SECURE WITH LID. 2. POUR IN THE WATER UNTIL THE JAR IS FULL. 3. PLACE THE CARD ON TOP. 4. TURN THE JAR UPSIDE DOWN CAREFULLY. 5. REMOVE THE CARD SLOWLY. 6. PUSH THE TOOTHPICKS THROUGH THE MESH PAINSTAKINGLY. 7. ADMIRE YOUR HANDIWORK. 8. TIP THE JAR AND WATCH THE WATER RUN OUT.
WHY THERE ARE ACTUALLY SEVERAL SCIENTIFIC PRINCIPLES AT PLAY IN THIS AMAZING SCIENCE MAGIC TRICK. THE FIRST IS ATMOSPHERIC PRESSURE (THE PRESSURE EXERTED BY THE SURROUNDING AIR). THIS IS THE FORCE THAT HOLDS THE CARD IN PLACE UNDER THE JAR. THE SURROUNDING AIR MOLECULES HAVE A GREATER FORCE PUSHING UPWARDS THAN THE WEIGHT OF THE WATER MOLECULES PUSHING DOWN ON THE CARD. WHEN WE TAKE AWAY THE CARD, SURFACE TENSION COMES INTO PLAY. THE SURFACE OF THE WATER BEHAVES AS IF IT HAS A THIN MEMBRANE STRETCHED OVER IT. A FORCE CALLED COHESION CAUSES THIS. COHESION IS THE ATTRACTION OF SIMILAR MOLECULES TO EACH OTHER. THE MESH/GAUZE FORMS A LATTICE ACROSS THE SURFACE OF THE WATER ENABLING THE WATER MOLECULES TO FORM STRONG BONDS TO ONE ANOTHER. THIS FORMS A MEMBRANE THAT STOPS THE REST OF THE WATER COMING OUT. WHEN THE JAR IS TIPPED ON ITS SIDE, AIR MOLECULES ARE ABLE TO BREAK THIS MEMBRANE AND SO THE WATER COMES OUT. WHEN WE PUSH THE TOOTHPICK UP INTO THE WATER THROUGH THE MESH/GAUZE, BUOYANCY COMES INTO PLAY. THE TOOTHPICK FLOATS/RISES TO THE TOP OF THE JAR BECAUSE IT IS MORE BUOYANT THAN THE SURROUNDING WATER.
QUIZ TIME Q1. WHAT IS THE NET I PUT ON THE JAR CALLED? A1. MESH Q2. WHAT WAS MY EXPERIMENT CALLED? A2. MAGIC WATER Q3. WHAT WAS STEP 7? A3./Q3. ADMIRE YOUR WHAT? A3./Q3./A3. HANDIWORK Q4. WHAT HAPPENS WHEN YOU TIP THE JAR? A4. THE WATER RUNS OUT
