Pop up stores have become a growing trend and a new one that has emerged in London is by the experimental culinary wizards Bompass and Parr. They have opened a Chewing gum factory where you can select from 200 flavours and mix them together to make your own. Such flavours include cotton candy, caramel, foie gras, champagne, mustard and mold!!
Other pop up stores include this one for Uniqlo in a metal container,
