Start your halloween party off right by sending out the perfect invite! This Halloween Lab Invitation is a creepy choice.  Plus, the bright blue, yellow, and green color scheme is a fun alternative to the traditional black and orange. Try a few of these other ideas to get your guests in the mood to party:
  • Send our Halloween Lab Invitation rolled up in a test tube along with green and blue confetti. Mail the invitations in small boxes or hand deliver! 
  • Download and print this free mad scientist lab coat invitation wrap.  It fits our 5x7 Halloween Lab Invitation perfectly and matches the color scheme, too!
  • Cut card stock to look like a science beaker, and write your party information on the front. (Get the kids involved by having them cut and decorate each invite!)
  • If hosting a kids' Halloween party, mail a plastic test tube filled with green DIY slime (don't forget to include the recipe) along with each invite.   They'll love the gooey, science theme favor, and they'll be excited to attend!
  • Go all out with a Custom Halloween Caricature Invitation!  You can design your own - a family of Frankensteins inviting guests for a spooky time, or a mad scientist (the wife) working on her laboratory monster (her husband) in her fully equipped lab!
After choosing your Halloween Invitation, decide on the perfect wording. And don't forget to let your guests know to arrive in costume. (You are dressing up, right? Right?) Try one of these fun wording options for a mad scientist theme:

Before even stepping through the front door, make sure your yard is transformed into the perfect creepy lab.  Follow these easy tips and tricks to make your party entrance a hit:
  • Cover a large table with a white tablecloth to make a "lab".
  • Scatter beakers, graduated cylinders, and test tubes with colored water  haphazardly along the table.  To create smoke coming from your "experiments", just drop in chunks of dry ice before guests arrive.
  • Don't forget your brain in a jar!  Fill a large clear jar with green colored water, and add a green cabbage that has been slightly disassembled and torn up to look like a brain.  Add green glow sticks to the jar for an eerie look.
  • String stretchy webs and plastic spiders along windows, bushes and your lab table. Every good mad scientist's lab is a little decrepit! Make sure to include a strobe or black light to set the mood, too.
  • Every spooky lab needs a monster.  With a Frankenstein Photo Cutout, that monster can be you!  Place your cutout near the door or behind your lab table for a surprise.
  • Finish your outdoor look with a custom Haunted Lab Theme Banner. It not only matches the yellow, green, and blue color scheme but coordinates with all of our other Halloween Spooky Lab Invitations and Party Favors, too!
You'll have fun turning your home into a spooky laboratory, too!  From decorating your guests to your spooky buffet, we have all the ideas you need:
  • Greet your guests at the door dressed as a mad scientist.  Add a crazy wig, goggles, lab coat, and long black gloves. Guests will love your die-hard commitment to the theme!
  • Don't forget to dress up your guests, too! Hang white lab coats on a rack near theentrance, and guests can transform themselves into mad scientists as they walk in.  (If you're providing costumes for your family and friends, make sure to let them know on your invite beforehand.)
  • For your sign-in table, creep guests out with jars filled with fake bloody body parts.  Add beakers fill with colored water and bubbling dry ice!
  • Turn your guests into monsters with a Frankenstein Halloween Party Photo Op. They'll love taking turns posing as everyone's favorite green terror! 
  • Make sure to hang stretchy spider webs in ceiling corners, around a chandelier, or along a mantle.   Add a black light to each room to make these eerie webs glow. Any white lab coats will glow too!
  • Don't forget chains for your lab monster! Make a few DIY Halloween Chains (check out the blog post how-to here) and hang them all over your mantle. Add spider webs, glass beakers, and test tubes along the mantle to finish off the creepy look.
  • Put black cauldron filled with dry ice and water into your fireplace. Everyone will love the smoke and bubbles! Add a green lighting for an eerie glow.
Don't forget - the hosts should dress up, too!  The host and hostess would make a great Frankenstein and Frankenstein's bride.  Consider renting a more elaborate costume, so family and friends can take their picture taken with this monstrous duo!
mad scientist table decorations and menu
Decorating your spooky lab tables is a snap!  Try a few of these easy tips to make your tables a hit with family and friends:
  • Match the theme's colors by decorating tables with bright yellow, blue and green tablecovers.
  • For centerpieces, collect a variety of scientific glassware - flasks, beakers, test tubes, and graduated cylinders are great!  Fill them with colored water, add dry ice and arrange them across tables as eccentric, mad scientist decorations.
  • Keep it simple! Place a Electrostatic Ball in the center of each table.  It fits the mad scientist theme and will keep guests entertained.
  • Fill a glass vase with glow necklaces, bracelets and glow jewelry.  This doubles as a centerpiece and party wearable!
  • Print out the Table of Elements on cardstock and cut out each square.  Scatter the "elements" on each table as confetti.
Keep the mad scientists and monsters at your lab party fed as well as entertained. Serve up a few of these spooky theme treats:
  • Frankenstein Pudding Desserts: Easy-to-make and delicious. Plus, this goody pays homage to everyone's favorite lab created monster. 
  • Petri Dish Jello:  Make green or blue Jello in petri dishes and add sprinkles (little bacteria) and gummy worms. Themed and yummy!
  • Mad Scientist Candy Buffet: Have family and friends fill a Halloween Lab Party Favor Bag with a variety of treats! Gummy worms, brains, rock candy, and pop rocks all fit the theme along with our Halloween Lab Lollipops.  Check out my Halloween Lab Candy Buffet for more inspiration.
  • It's Aliiiiiivvvve!!! Cupcakes:  Have guests create their own lab cupcakes! Set out containers of frosting (blue, green, and yellow theme colors, of course!) and fun spooky toppings; try crushed Oreos, gummy worms, Halloween sprinkles, marshmallows, and eyeball gumballs. 
  • Halloween Lab Water: These Halloween Lab Water Bottle Labels will dress up your table, and they match our other Halloween lab party supplies, too.
spooky lab theme activities and games
A mad scientist theme is perfect for kids, so make sure your littlest guests are entertained with fun mad scientist experiments!  One or two of these fun activities should keep them entertained for most of the party:
  • DIY Green Slime: Make your own stretchy green slime with a few simple ingredients from the grocery store (glue and Borax).  Have guests take their slime home in a plastic test tube as a favor! 
  • Underwater Fireworks: Another easy activity!  These slow motion fireworks are perfect for pictures.  
  • Atom Building:  Have the kids build "atom structures" with gum drops and toothpicks.  Yummy and fun! 
  • Bubbling Beakers: Guests can mix vinegar and baking soda in scientific glassware to create an explosive experiment (add food coloring to the vinegar)! Make sure to perform this experiment on cookie sheets or outside for eacy cleanup
Set up a spooky photo booth with a bunch of kids halloween photo props! Little monsters will love having their picture taken in front of a spooky lab backdrop.  Print the pictures at the party, so guests can take them home as favors!
