Colorful Science Flasks Card

I had so much fun making this colorful science flasks card with the new It’s a Science stamp set! Watercoloring a rainbow was a great way to make these flasks and beakers stand out for this birthday card.

Science has been such a huge part of my life, and when this stamp set came out in the new catalog, I knew I needed it to make some fun projects.

The different colors in each of the flasks could be indicating what’s inside, the reactions that are occurring, or the pH level, so making them into a rainbow of colors on this card was fun and a reminder of things changing.

Can’t decide between the Erlenmeyer flask, the beaker, the Florence flask, or the tube? Don’t stress and use them all!

How to make a colorful Science Flasks Card:

Cut your cardstock:

  • Basic White: 8-1/2” x 5-1/2”, score and fold at 4-1/4” for your cardbase, and a scrap for the science flasks
  • Orchid Oasis: 4” x 5-1/4”, and a 3/4” scrap for the sentiment
  • Watercolor paper: 3-3/4” x 5”.

TIP: When watercoloring a background, cut the paper larger than your final size and trim it after it’s dry. This then gives you space to tape down the paper without affecting the painted design.

Watercolor the rainbow of colors:

  • Wipe the wide water painter over your yellow ink pad, squeeze a small amount of water onto its bristles, and swipe it down the center of your watercolor paper. Do this repeatedly until your are happy with the amount of color.
  • Then repeat this watercoloring with the other four colors. Let dry.
  • Next, stamp the bubbles at the top with black staz-on ink and adhere to the Orchid Oasis piece.

Make your science lab:

  • On a scrap of white, stamp the science flasks and tube with black ink. Then color them in with markers that coordinate with the colors you watercolored with. Cut out the flasks as one piece and adhere to the card front with dimensionals.
  • Stamp the birthday sentiment on the Orchid Oasis strip with versamark ink, sprinkle with white embossing powder, and heat until shiny. Adhere it to the front, and trim the excess over the edge.
  • Lastly, adhere the colorful science lab to the white card base.
