When I built my egg drop I had it planned out before I built it. I crossed 4 sticks. Then I put 4 sticks going up. Then I doubled up 2 rubber bands and put cross wise. Then I got to big sticks and glued them in a cross. Then I drilled holes in them. Then in the holes I put the yarn in the holes and attached it to my parachutt.
I dropt mine first, mines didn’t crack. I was so happy it didn’t crack. I was super nervous. I think mine did good. I let it go and it just floated down. I think some peoples needed improvement. I think mine could use a little work too.
