My kids had so much fun making potions in a cauldron with their friends earlier in the year. I knew this could be one of the best parts of the party. I had been wanting to create potion bottles for Halloween anyway so I was excited about this because I knew I could reuse them for that purpose after the party. That part was easy.
But what to mix the potion in. I knew one big cauldron would be a disaster as I'd already witnessed the arguments about who gets to add what ingredients to the potion. Each child needed their own container to mix in. Preferably something that was water tight so the kids could take their potions home with them. Fortunately I'd been saving large jam jars so I had a good start but with 16 kids I was going to need a few more so I saved jars for a month prior to the party. Just cleaning the labels off was a job.
They turned out cool and I know my kids will continue to make potions in theirs for a long time.
