Today we had to build tunnels so our car could fit in our tunnel. first we had to do get into a group of 4 people then we had to draw a tunnel so we could get idea. Then we had to make a tunnel so we had to get some straw and spaghetti. So we could build our tunnel then we had to get Sellotape so it can stick together when we finish we had to put glad rap around the tunnel so sand couldn't get thorough.Then we had to put sand over it and see if it would survive our tunnel won.
