It appears you are describing a science experiment where you are testing different materials to see if they can be used to make a "car" move. Here's how you might fill out the table, assuming you are using a simple "car" design like a toy car with a balloon as a power source: Material Does the car work? (Y/N) Time of Travel Observations Aluminum foil N - Aluminum foil is too thin and flexible to hold the balloon securely. It might tear easily. Plastic wrapper N - Similar to aluminum foil, plastic wrap is too thin and flexible. It might tear or stretch too much. Paper N - Paper is not strong enough to hold the balloon securely. It will likely crumple or tear. Wax paper N - Wax paper is similar to regular paper in terms of strength and will likely tear. Cotton N - Cotton is soft and absorbent. It won't provide a rigid structure to hold the balloon. Rubber glove Y (Record the time) A rubber glove is a good choice because it's stretchy, can be tied securely around the balloon, and will hold its shape.
