Barbie Bungee Data Estimates

I think that the drop distance would be 163cm if we hand 10 rubber bands. If we had 20 rubber bands the drop distance would be about 207cm. If we had 30 rubber bands i think that the drop distance would be around 350cm. I estimated     the drop distance see the data that we got when we had 8 rubber bands. And jest by comparing the data we  got and the jest estimate the drop distance.
