Sold out We decided adding a splash of science to our favorite day of friendship sounded super fun! Invite your favorite friends who love getting their hands dirty. We’ll make homemade playdough and add a splash of scented rosewater oil to add to the multi-sensory experience. And it doesn’t stop there–next, we’ll make fizzy exploding hearts! Top it off with some Valentine card making with candy hearts, and we’ll call it a Valentine day!
