Decorating a Mad Science Lab

Sharing is caring!

Make one party room/area into the lab. It will be much easier to decorate and will contain 

1. On the entrance to the room– put up some danger tape and a notice warning that only scientists may enter the “Secret Science Lab Zone”.

2. Using black construction paper cut out large question marks, magnifying glasses and mathematical formulas. Put these up around the room.

3.  Put up posters of famous scientists around the room with a small caption underneath of why they are famous.You could also hang some science clip art pictures in the room. These can be found with an internet search such as Google.

4.  Decorate the space with an array of lab items such as gummy frogs that have been pinned down so that they look as if they were being dissected. You can also keep jars of lab specimens such as huge gummy snakes, lizards etc.

5. Check out Halloween stores/sites/for slimy table decorations which are perfect for scientists; also skeletons, skulls and other gory accessories. If you’re going for a spookier look–purchase cobweb/spider webs from Halloween stores and put them about the room on tables, etc.

6.  A dry ice machine would make a great table center piece.

7. Fill lots of different shaped jars with colored water and rubber body parts to put around the table.

8.  Borrow microscopes, chemistry sets, molecule models, magnifying glasses, compasses, and so on, and place them on the table and about the room. Do you have a flickering plasma lamp? Kids of all ages love them!

9. Use a colored globe light to give the room an eerie appearance or just place colored light bulbs in regular lamps.

10. Set up a large chalk board/white board and write the recipes for the experiments that you are going to do.

11. Hang a sign from the table or at the doorway saying “Welcome to the Science Laboratory”.

12.  Use a ‘weird or scary font’ to write signs such as “Electricity”, “Gas”, “Chemicals”, and put them around the area.

13. Put a rubber band around several large test tubes. Tie a ribbon over the rubber band. Arrange tubes to stand with open ends up. Fill them with colored water and add a flower or two.

14. Make a Light Bulb Pinata–Click here for directions! (And Photo)


 #1 Professor X Lab Coats: Cover the table with newspapers or freezer paper. Lay out fabric markers. Give each child a plain white shirt to decorate as a lab coat. You can use T-shirts, or look for used front-buttoning shirts at thrift shops

Idea #2
Use white kitchen sized garbage bags to make lab coats (A practical way to protect children’s clothing during experiments)
Cut a half circle hole for the head, and half circles for the arms. With a black permanent marker, draw a line down the front and buttons next to it. You can also draw a pocket on the side with a pen in it; write the children’s names on them (Example: Professor Smith, Dr. Susan.

Purchase black party glasses with the noses and mustaches from a novelty or party store. Before kids enter the “science lab” have them don their coats and glasses. It would be great if party facilitators could be wearing white lab coats, crazy wigs, goggles, or glasses too! BE SURE TO TAKE PHOTOGRAPHS of this! Kids may not leave these on long—but it will be great fun.

Food itself lends itself to the decorating! Make sure it’s creepy, gooey and gross! Visit the Mad Science Theme for ideas on games, experiments, snacks, and more. Also check out the Halloween Snack and Party Food category for creepy, crawly goodies!



For truly dramatic effects, create fog using dry ice. Add one piece of dry ice to every gallon of very hot water. Note: Be careful and make sure that it is in a place where children cannot hurt themselves. (See complete directions below)

CREATE A ‘FOG EFFECT’ with dry ice

Materials needed: Large container
Lot water
Lry ice
CAUTION: Only use dry ice in a well-ventilated area. The carbon dioxide released from dry ice will displace oxygen.

Fill a metal or plastic container half full with hot water, add a few pieces of dry ice every 5 to 10 minutes. As water cools, it will be necessary to start over with hot water to maintain the fog effect.

As a rule of thumb, one pound of dry ice will create 2-3 minutes of fog effect. The hotter the water, the more fog but the quicker dissipation of the dry ice.

When you place dry ice into some warm or hot water, clouds of white fog are created. This white fog is not the CO2 gas, but rather it is condensed water vapor, mixed in with the invisible CO2. The extreme cold causes the water vapor to condense into clouds. The fog is heavy, being carried by the CO2, and will settle to the bottom of a container, and can be poured. You can produce enough ground – hugging fog to fill a medium-sized room with a pound or so of dry ice. Do not allow anyone to lie down in this fog, or allow babies or pets into it, as CO2 gas does not support life. Source: continentalcarbonic


Whether you call them nebula spheres, PLASMA LAMPS, or lightening balls, these lamps put on one of the most unique displays available. Twenty years ago they cost $1500. Today you can get one for $40.00 or less…
Technically, they’re a clear glass orb, filled with a mixture of various gases at low pressure, and driven by high frequency alternating current at high voltage…Great for decorating a ‘Mad Science Lab’!!!
