Recovery System

Today i worked with Kimmy and Kathryn. We started by designing a parachute and securing a sand bag to it using string, hole puncher, plastic bag, and hair dryer. We started by cutting up a big plastic bag because it was too big. We tied four strings from the bag to the weight. This created strength and an equal balance. When we tried it by filling it with hot air, it still fell pretty easily. So I came up with an idea to add a second parachute above the first like a bi-plane. All though we never got to try this, we think it wouldv'e worked because the air wouldv'e flown through the two flaps to create lift, and it would go up slower so that it wouldnt come down to fast because of Newton's 3rd law
