It's time to head back to the classroom and loads of you will be picking out your new school gear!
A survey reckons that this year, school bags could be filled with almost a mega £200 worth of gadgets.
We want to know what weird things you've found in your school bag?
Perhaps you've spotted a mouldy yoghurt pot at the bottom of your backpack? Or maybe you found a fiver you thought had gone forever?
Whatever it is, we want to know!

"In mine I found rocks, which were for a project for school but I was to lazy to take them out, some crumbs, from an old snack probably, a water bottle, a piece of paper with emergency numbers on it, a drawing, a blank piece of paper and a hole at the bottom of the bag, probably from the rocks."
