Get some fire poi. Even if you don’t know how to do poi. Just practice a little spinning them in a simple circle on each side until you are comfortable with that. Then light them and do the same. Experiencing them simply spinning with the whooshing sound as well is quite blissful. If you end up tempted to learn more, get some training ones. Do not try with the fire ones, there’s metal there and it’ll be a while before you stop smacking yourself in the nuts!
