We discovered that there were pencil shavings in the paper bin. It was bad because worms can't eat them so we had to seperate it all with tongs. We also saw tissues that the worms couldn't eat - we compost tissues. It took us a long time to separate the rubbish. It took us probably 30 minutes or a bit more to sort out the rubbish. We were so tired we had to have a rest but it was also fun. We even had fresh air and we took turns. We only had 3 in our group so we all had to take turns sorting the rubbish.
