Teal Flask and Bubbles Painted Science Pumpkin

Clean and dry the pumpkin

Wipe the pumpkin surface with a dry paper towel and let it sit for a few minutes to ensure the surface is fully dry. Any moisture interferes with acrylic adhesion. Choose the flattest face for the painted design.

Sketch the flask and bubble layout

Draw the Erlenmeyer flask outline in pencil, centered on the pumpkin face. Mark a horizontal liquid level line about halfway up the flask body. Sketch five to eight small circle positions around the flask for the bubble cluster. Adjust the sketch until proportions look right before painting.

Block in the flask base color

Fill the entire flask outline with a medium teal acrylic in two even coats using a flat brush, letting each coat dry fully. If teal reads too green or too blue on your pumpkin, add a small amount of white to the mix to lighten and brighten it. Two coats should give solid, opaque coverage.

Paint the liquid area a darker shade

Mix a slightly darker teal by adding a touch of blue or black to your base color. Paint the lower portion of the flask body below the penciled liquid line with this darker shade while the base coat is dry. A clean, straight liquid line at the top of this area is the key detail that gives the flask depth.

Add bubbles and sparkle accents

Dip a round foam sponge dauber, a pencil eraser, or a fingertip into white acrylic and dot the bubble circles around the flask. Vary the dot size slightly for a natural bubble cluster. Add two small four-point sparkle accents near the flask using a thin detail brush and white paint.

Seal and display

Once all paint is fully dry, apply a thin coat of matte craft varnish over the entire painted area. Let the varnish cure overnight. Display the pumpkin on a desk, shelf, or event table. Its intact shell means it will last several weeks with no special care.
