When choosing sparklers, you want to consider if you are going to be taking photos or not. If so, you want to use longer sparklers such as the 20″ that will burn for a good 2 minutes. I also like to recommend giving each guests 2 sparklers. It typically means you will get sparklers burning for a good 3 minutes, they fill in more space which is great for the photos. There are so many suppliers now for buying sparklers online and at an affordable price.
