Participants customize their creations with colors, glitter, scents and Halloween-themed charms, then name and label their potion. Everyone leaves with a bottled slime potion to keep or give away, so it is a hands-on, slightly messy activity that young kids and older siblings can enjoy together. ## Similar picks coming up in Boston - [The Salem Haunted Magic Show: HYSTERIA: Ghost Psychic!](https://grassyknees.com/boston/activities/the-salem-haunted-magic-show-hysteria-ghost-psychic--listing-8ae57d927dd60196bda75209) — Fri, Nov 6 · Emerson Hall Theater, Salem · All ages · checked Oct 30.
