It needs to hold a minimum of 15 marbles and stay floating for 30 secondsONLY USING:1 5quot;X5quot; sheet of aluminum foil.5 strands of uncooked spaghetti1 15 cm strip of masking tape (1/2 inch width)
Don't know that i can help with this, but keep one thing in mindeach of your items will float, except the marbles of coursemake a container or boat shape with the aluminum foilyou can tape the spaghetti to the bottom with masking tapethis will help hold the weight of the marblesmake the edges of your container doubled overthe sides can touch the water which will also help it floatyou may have to adjust the shape of your container so that the marbles are evenly distributed in the containeryou may have to crush the aluminum foil before startingThis will make it stronger and harder to sinkBut after all is said and done, it still trial and error.
