RAFT BUILDING

For a boat to float it has to push its weight in water down wards Yesterday afternoon me and my class were making rafts and we were using materials like bubble wrap, cardboard, foil, sticks,tape,caps, and a hot glue gun. First, we got the cardboard tape bubble wrap foil sticks hot glue gun we started building our raft so first we got cardboard

d then wrap it with bubble wrap then we wrap the bubble wrap with foil then we taped all of that.After that we glued the sticks to the raft then we made a flag to put on the raft then we tested it to see if it would float or sink and it floated so we tried to make it sink by moving the water and it still wouldn't sink so you guys should give it a try.
