electricity with a neutrally charged balloon What results do you expect? I expect that the balloons charges and sticks to the wall. What is the result are different? That would mean that there is a different way to charge the balloons than negative charge as using your hair. EXPERIMENT Bring together the balloons but not touching each other. Rub a balloon in sweater. Rub several times the balloon and the sweater so there is more attraction Bring the balloon as close to the wall as possible

Jeff Koons’ Balloon Dog (Yellow) This essay discusses the sculpture Balloon Dog (yellow) (1994-2000) by American artist Jeffrey Lynn Koons (b.1955). I will explain how Koons uses the Balloon Dog (yellow) to talk about both childhood experience and sexuality‚ and uses these ideas to manipulate the viewers’ emotion.

2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden skewer •

Materials: * 1 un-inflated balloon (when inflated‚ the balloon should have a round shape and be approximately the size of a soccer ball) * Markers * About 30 cm (12 inches) of string or yarn * Ruler or tape measure Procedures: 1. Place an un-inflated balloon on a table. The balloon represents the universe. Use a marker to make small‚ filled-in circles on the balloon. The circles represent

is to demonstrate how water temperature affects the volume of a balloon. According to Charles’ Law‚ temperature and volume increase proportionally‚ as long as chemical amount and pressure remain the same. Research Question: How does the volume of a balloon react to changing temperatures? Hypothesis: If we increase the temperature of the water‚ then the balloon will expand. If we decrease the temperature of the water‚ then the balloon will contract. Materials and Procedures: Manipulated Variable:

IceBridge‚ is used to measure the ice elevation of the landmass that the aircraft is flying over. In order for a laser altimeter to be used on a super pressure balloon the weight and size of the instrument must be drastically reduced‚ continuing the trend of the need for much smaller and lighter equipment for use on super pressure balloons. The purpose of the altimeter would remain relatively the same‚ although the effectiveness of the instrument would be hampered. For one‚ scientific planes usually

experiment you can prove that electric charges can produce by using only a balloon and pieces of papers you can understand further static electricity and charges. And how it is produced. Introduction Have you ever wondered why rubbing a balloon make pieces of paper attract with it? The effect is due to static electricity‚ but how is the static electricity made‚ and why does it make pieces of papers attract in the balloon? Static electricity is the buildup of electrical charge in an object. Sometimes
