Get ready for a night of tricks, treats and Halloween mischief! W5 is staying open after dark for a frightfully fun family night packed with creepy creatures, ghoulish games, spooky science and plenty of surprises. Dress up your little monsters, grab your Halloween bags and get ready to explore W5 after dark, if you dare! From hunting down Trick-or-Treat Stations around W5 and taking on the spooky challenge of Splat the Bat, to getting Halloween-ready with face painting and balloon modelling, there’s something to keep little monsters entertained all evening. Meet weird and wonderful creatures at the Live Animal Encounters, dance along at the Monster Mash Disco and show off your best Halloween looks for the chance to WIN a W5 Membership in the Fancy Dress Competition. Plus, don’t miss the Pumpkins and Potions Live Show, packed with eerie experiments and bubbling concoctions, or step into Spooky Square and help Boo Ghost uncover its Halloween mysteries. And when your adventure comes to an end, enjoy 15% off everything in the W5 Gift Shop on the night. It’s a Halloween night the whole family will love, with plenty of fun, surprises and spooky discoveries around every corner!
