Wacky scientist Ann Dale led the science-based practical fun for 32 children who attended.
An afternoon of Halloween witchery fun was enjoyed at Market Rasen Library when Ann visited with her potions and experiments.
Lava lamps, ghoulish ghosts and dancing skeletons kept everyone entertained.
They had great fun making shadows with spooky articulated skeletons and seeing how many tissue paper ghosts they could float using just balloons and static electricity.
They also made fizzy lava lamps, using oil, water, food colouring and fizzy tablets during the hour-long session on October 23 that Ann said was “truly amazing”.
“It was fascinating for so many and great fun too… Children and adults alike,” she said.
Ann staged similar science-based Halloween sessions at Louth library, where she had a Harry Potter theme, and in Gainsborough giving a dry ice extravaganza.
