THIS EXPERIMENT DEMOSTRATION SHOWS HOW MOLECLUES ARE FAR APART. AIR IS A GAS ALL AROUND US. AIR CONSIST OF DIFFERENT GASES OXYGEN IS ONE OF THEM, AS THE PAPER BURNS IT USES UP THE OXYGEN IN THE GLASS JUG. SINCE THE EGG SEALS THE NECK OF THE JUG NO MORE AIR CAN GET INSIDE TO REPLACE THE USED UP OXYGEN AND THE FLAME CEASES TO BURN. IN THIS PROCESS THE BURNING CREATES A VACUUM.
