Create a fun and fabulous "Laboratory of Love" Backdrop for a Science & STEM themed Valentines day celebration. Your guests will be sure to "fall" for it!

This bubbling balloon potion & periodic table was created as a backdrop but would make for a fun photo booth as well.

Follow the "formula" below, it has all the "elements" you need to set up the perfect Valentines' laboratory scene with a few simple party supplies.

First using red masking tape create the outline of a science beaker.

The height of the beaker should be approximately double the width of the bottom. The top opening of the beaker is approximately 1/3 of the length of the bottom.

Tip: Use a small level to get the top and bottom lines of tape straight.

Next, cut pieces of tape in half-length wise to make them skinnier.

Use these strips of masking tape to create measuring lines on the side of the beaker.

 

Then use glue dots to attach a Glitter Valentine Foam Heart at the end of the measuring line.

Continue until you have made 4-5 equally spaced measuring lines.

Next, download the "periodic table" here. Use this as a guide to how each element is represented.

Use a chalk pen to copy the letter, number and name of each required element onto each square.

I used - H P P Y V Al Ne Tl Ne S Dy to create Happy Valentines Day.

Alternatively, if you have a cutting machine the periodic elements are available in the library.

If using a cutting machine you have the option to cut either white letters or do a reverse cut in white vinyl to get pink letters (as I did above).

Then attach the finished elements to the wall using glue dots. Use the first Ne upside down to get the closest spelling.

Next, using a Hand-Held Air Balloon Pump blow up Valentine Heart Print Latex Balloons and some Lavender Balloons.

 

Tip: For this size garland I used two packs of Valentine Heart Print Latex Balloons.

 

Insert the balloon tails into the holes of a 25-Ft. Balloon Decorating Strip, alternating color and design until complete.

Finally, hang the balloon garland from the wall using a removable hook at each end. Have the garland hang down to meet the top of the science beaker.

Secure the balloons in place at the top of the beaker using glue dots.

You can now go ahead and set up your laboratory dessert table or supply station under the backdrop.
