You need:

• Cut plaster strips of approximately 3 cm x 30 cm (about 5 per jar).
• Fill a bowl with water and dip the plaster strips into it.
• Place the wet strips on the jar from top to bottom.
• Let the plaster strips dry for a few hours.
• Once the strips are dry, apply glow-in-the-dark paint on them.

Tip: for even more glow, apply a second coat of paint.

• Cut out the eyes from the black adhesive foam sheet and stick them onto the jar.
• Draw Frankenstein's mouth with a black paint marker.
• Decorate the top of the jar with Halloween sequins and spider web.
• Turn off the lights to admire the result in the dark!
