Here are some tips to help your Science Lab party go off with a bang!

Science Lab Party






Some ideas for what to feed them:

The main: Why not keep it simple with sandwiches, pitta, pasta salad or pizza for the main (make sure you have a vegetarian option).

Vegetables: crudites like carrots, cucumber, peppers and celery which you can serve with hummous are easy to prepare and go down well as do olives and iceberg lettuce.

Fruit: Go for fruit that doesn’t need to be cut up like berries and seedless grapes and fruit that doesn’t spoil when cut like melon and mango…

Treats: A few treats are a must on the party table. Biscuits, popcorn and crisps are usually popular.

Ideas to theme your food:

  • Cut your sandwiches with flower biscuit cutters to make them into molecules
  • Use flower or lab equipment biscuit cutters to shape homemade biscuits
  • Make edible fruit molecules with the cocktail sticks from your Edible Molecule Activity. Grapes, blueberries or olives would work (but maybe not mixed together!)  You could even get the children to make these themselves.
  • Serve DNA fuisilli pasta salad
  • Label water bottles with H20 (you could also put the children’s names on the labels so they don’t get mixed up)
  • Serve atoms. These could be sweets such as smarties or fruity atoms such as berries or melon balls for a healthier alternative.



Here are some extra party game ideas you can do with items around the house

Mentos Coke Geyser Explosion: Add 5 or 6 mentos to a 2 litre bottle of coke then stand back as the coke will explode! (Best to do this outside!)

Cornflour Slime Experiment: Place 50g cornflour per child in a bowl. Add 55ml of water. (Optional: add a few drops of food colouring to the water if you want it coloured). Mix together and enjoy playing with the gloopy slime! (Do not dispose of down the sink – place in a zip lock bag and put in the bin).

Excited Molecules Balloon Race: Line the children up in two lines and give each line a molecule balloon. Then have a relay race keeping the two molecule balloons up in the air the whole time!

Molecule Tag: Children play a game of tag and create molecules by linking arms when they have been tagged. When they have a molecule of 4 children then they start again with a new “it”.

Piñata: These are available to buy on amazon and come in a variety of designs. You could turn a football into an atom by covering with tissue paper. Simply fill with sweets and treats such as stickers, tattoos etc and confetti or torn up tissue paper if you like. Then hang the piñata up and let the children whack it with a soft bat. When it is broken open then shake the remaining treats and confetti over the children and let them gather them up and put in their party bag. Top tip: make sure children who are not taking their go stand well back and keep a few treats back in case of someone missing out on something.

The Doughnut Eating Game: string up some doughnuts and see who can be first to eat their doughnut with hands held behind backs!



Guess How Many Sweetie atoms are in the Jar: to win the jar of sweeties!

Molecule Balloon Pass: Line children up in two lines and race to pass the balloon along the line, first over the head and then through the legs!

Flour Mountain: fill a pudding bowl with flour and then turn over to create a flour mountain. Place a jelly baby on top and children take turns to remove a spoonful of flour without toppling the jelly baby. The one who knocks the jelly baby off must eat it with hands behind their back and gets a face full of flour!


Party Game


Suggested Running Order

We reckon around two hours is the perfect time for a party to last and between 6 and 8 activities should fill the time.

  1. Put on Party Music
  2. Hand out Science Goggles to your guests as they arrive
  3. Begin with the Edible Molecule Activity (which stragglers can join in with when they arrive)
  4. Free Play with balloons and/or another Party Game or Activity (see above)
  5. Explosions Game
  6. Atom Pass the Parcel (if you have one)
  7. Party Food
  8. Fizzing Science Experiment
  9. Free Play with balloons or another 1 or 2 Games or Activities (see above)
  10. Cake
  11. Hand out Party Bags and Swirly Lollipops as they leave

  • PREPARE THE EXPLOSIONS GAME: Divide the confetti equally and stuff it into the clear balloons. Top tip: We have found that the best way to stuff a balloon is to use a funnel or make one out of cardboard. Walk the index and middle fingers of both hands down and into the neck of the balloon, being careful of nails. Carefully stretch the opening over the funnel ensuring that the funnel leads directly into the wider part of the balloon. It is quite easy to tear the balloon so take your time. Then gently feed little clumps of confetti into the balloon. Take a look at our video tutorial . You can check out our Party Tips for an alternative method if you find that tricky. 

Explosions Activity


  • PREPARE THE FIZZING EXPERIMENT: Gather the ingredients you need (bicarbonate of soda, white vinegar and squirty hand soap – food colouring optional)

Fizzing Experiment Activity



  • MAKE AND ICE THE CAKE (If you are making one).




  • BALLOONS AND DECORATIONS: Inflate the balloons using the included pump. (or you could do this the night before to save time). The standard sized balloons are 11”, the giant balloons are 36” and the tiny balloons are 5”.

Top Tip: You can use a hair dryer on cold setting to pump up the giant balloons as they can be tricky to do with the balloon pump. First inflate the balloon a little with the pump or your breath then attach to the hair dryer and blow until it is the right size. Try not to over-inflate the balloons as this increases the risk of them popping. Also keep giant balloons out of the sun as we have found they can pop in direct sunlight! Giant balloons are a lot of fun but they can knock things over so make sure you move your valuables from the party room! Take a look at our video tutorial on how to do inflate giant balloons with a hair dryer. 

Place the confetti balloons for the Explosions game in the balloon bag provided. (We realise the bag is a tad big! – but you could use it to store all the party the balloons if you blow them up the night before and it can also be used for rubbish when it comes to clear up). Then simply drape your fringe garland.

  • PARTY TABLE: Set out your tablecover, paper plates, cups, straws, napkins and sprinkle your confetti over your party table

  • PREPARE THE FOOD: See above for ideas.


  • PREPARE THE CAKE: If you have a Cake Decorating Kit, scatter over your smarties, arrange your Happy Birthday candle and glitter candles and finish by sprinkling on your explosive popping candy. Top tip: do this just before you serve as it will start popping when you put it on the cake!

  1. Goggles
  2. Bicarbonate of soda, squirty hand soap and white vinegar with trays, beakers and spoons for Fizzing Experiment.
  3. The Explosions game in the balloon bag. Top Tip: Get the kids to help tidy up after the game without realising by telling them there is a prize for whoever collects the most broken molecules! (bits of balloon) The prize can be something as simple as a pack of fruit yo-yos or sweets and you can give them all one…
  4. Edible atom jelly tots and cocktail sticks for Edible Molecule Activity (you could put all the jelly tots in one or two bowls or separate them into individual containers for each of the children.)


Science Party Edible Molecule




What they should go home with: Top tip label your party bags and make sure kids add any prizes etc they get during the party so you can make sure they go home with all their loot.

  1. Swirly lollipop
  2. Their very own Edible Molecule (if it hasn’t been eaten!)
  3. Science goggles
  4. Beaker
  5. A slice of cake (optional)
  6. Balloon tied with ribbon (optional but it helps with the tidy up!)


Science Lab Party Kit

You have fabulous science goggles in your party kit but if you want to get a white lab coat for the birthday child to complete the look then click the link above.

We hope you have a fun party and your little one has a big day to remember! If you don’t already have a Science Lab Party Kit they are available from Kit & Caboodle.
