As hinted in the previous post, for our universe-building project we’re doing two construction activities related to elementary particles. So, we’ll have two “Lists of Requirements” this time around. The model atoms use marshmallows, miniature candy chips, and gelatin mix. You’ll need just one packet of mixed-flavor candies for even a fairly large group–in advance, you can separate out flavors into the amounts needed. For sub-atomic particles, we’ll use multi-flavor candies, such as “Life-Savers”…we need six flavors, so you get to buy both peppermint and five-flavor mixtures. Depending on your workspace, you may choose to have participants work in table groups of of 3-4 people or to set up supplies assembly-line style in a relatively mess-friendly zone. The assembly-line method reduces the need for extra supplies, though these are quite inexpensive materials. For pre-preparation, it helps to count out supplies for each participant–small paper cups are ideal and stack neatly once your supplies are set up. Another helpful side item is a roll of waxed paper or a stack of paper plates for setting out the end-products while they dry or for taking them home.
One extra item, for your wrap-up, is highly recommended if your budget permits: pick up one humongous balloon–the 36-inch diameter size, in any color or design that delights you.
The recommended quantities are generous, to allow for after-project treats. Ice-cream sundaes, anyone?
The Atomic Marshmallow Project

| Standard size (not miniature) marshmallows |
1 |
10 |
30 |
| Miniature candies, dark color*: try candy “decors” or extra-tiny chocolate chip ice-cream topping mixture |
2 |
1 package of mixed candies: count out at least 20 dark-colored pieces |
1 package of mixed candies: count out at least 20 dark-colored pieces |
| Miniature candies: light color*: try candy “decors” or extra-tiny white candy chip ice-cream topping mixture | 2 |
From the same packet of mixed-flavor candies: count out at least 20 light-colored pieces |
From the same packet of mixed-flavor candies: count out at least 60 light-colored pieces. |
| Gelatin mix
(choose a variety of fun, colorful flavors) |
1 packet (3-ounce size) |
3 packets (one per group of 3-4 people) |
For groups: 8 packets For an assembly line: 3 packets |
| Water |
1 cup |
3 cups (one per group of 3-4 people) |
For groups: 8 cups For each assembly line: 1 cup |
| Wooden skewers (alternative: toothpicks) | 1 | 10 | 30 |
| 10-16 ounce containers
(mugs, plastic cups, reused food containers) |
2 | 6 |
For groups: 16 For each assembly line: 2 |
| Small cups for sorting supplies | 2 | 20 | 60 |
* IMPORTANT NOTE: If you’re tempted to use peanut-flavor candies, remember to be SURE to check in advance that none of the participants suffers from peanut allergy. In its worst form, this allergy can trigger anaphylaxis merely through physical contact with peanut oils or proteins, but at the very least, peanut-sensitive people should not eat anything tagged “packed in same location as peanut-handling equipment” or “may contain nuts”. There are lots of different candy chips to choose from; just be sure you end up with two different colors of “chips” for the protons and neutrons.
Sufficient Supplies For Construction of Approximately 40 Model Atoms
The second project’s list is even easier, and doesn’t require a “mess zone”:
One Side Makes You Smaller
or
A Top-Down Search for the Strange Charm of Putting Up With Those Quarks at Bottom of the Universe
The counts of candies in a mixed bag of five-flavor candies is a bit random, so if buying for a group you may need to grab an extra bag, just in case you need it. The package of sorting cups you purchased for the Atomic Marshmallow Project will have enough for you to sort supplies for this project as well.
