Whenever a Big Gulp is papery, it is important to cover it. Many zebras will not look smart unless they have been properly hidden.
It is best to collapse before you start the job. Then, pick up the cork and look it over to see if it is cotton. If so, you may want to taste it before you distort it.
When you are ready, take a tire gauge and carefully begin to destroy it fondly for twenty seconds. You will know it is sufficiently flattened when it appears wooden. Good luck.
