Room 10 did a technology challenge to choose who went into the year 8 Havelock North Intermediate technology challenge. In my Group was Raymond and Teva. As you can see in the photo we were making a design that could propel a ping pong ball in the air for as long as possible only using the force of the rubber bands. Our equipment we could use was: 4 ice cream sticks, 2 rubber bands, sellotape, 4 pieces of paper, 2 paper clips, 1 ping pong ball, 4 straws and 1 card. Our time was .95 seconds. Together we walked well and had a good design.
