Earthquake Structures with Gelatin Shake Trays
Yes, gelatin. Jello. I know that sounds scary, but it was really not. Keep reading…
- Do not pull the marshmallow apart. It must be used whole.
- After sticking a toothpick through a marshmallow do not pull the toothpick out. (It leaves sticky fluff on the toothpick.)
- Do not break toothpicks.
- If you need a hole in the cardboard for the toothpick, use tools. Do not attempt to pierce the cardboard with the toothpick.

So, we recently tried this challenge again! I love to try new things so I completely experimented with this Earthquake Challenge. First, we tried a new shake table!
NEW Shake Tray
- a plastic bin (mine is 23.5 x 16 inches and is about 5.5 inches deep. It’s called an “under-the-bed” bin)
- a piece of foam board (I buy mine at Dollar Tree)
- A long piece of one inch wide elastic or ribbon
- 4 large binder clips
- Cut the foam board so that it fits inside your bin with enough room to move in all directions.
- Use a box cutter to cut slits into four spots on the foam board. I measured and placed these evenly and cut long slits instead of large holes.
- Thread the elastic or ribbon through the slits.
- Use the binder clips to attach the elastic or ribbon to the plastic bin.
More Marshmallows – with the New Shake Table
These two materials work well and kids really like the uniqueness of food as a building tool. In the photos above you can see some of our creative structures and the new tray being used.
Hmmmmm…. what else can we try?
The next class used straws and tape. Again, I limited the tape so the kids would really have to think.
By the way, do you know how hard it is to tape straws to cardboard?
Some things we learned:
- If you can make a hole in the cardboard, craft sticks and straws work really well. If the teacher says you cannot make holes, then you have to get creative.
- The shake tray was excellent. We did find that the structures would slide too much without toppling. So, we tried putting a tape roll under the structure to hold it in place. Some of them toppled anyway. The tape just kept them from sliding around.
- I loved all three ways we tried this challenge.
