Melt-Proof Container

for all of your keeping-cold needs!!

A team of semi-expert 8th grade scientists(left to right: CLAIRE THOMAS, ZACH RICHARDS, KARLEIGH MEADOWS, NICK WITHROW) were given a challenge. Many food products these days are made very far away and it's hard to keep them cold/frozen. We were asked to create what we think would be a melt-proof container. This worked for the most part, but there were some complications. Below you'll find our process of how we created our melt-proof container.

MATERIALS:

  1. ALUMINUM FOIL (3.3 FEET)
  2. STRAWS (4)
  3. FELT (ONE SQUARE; RED)
  4. TAPE (2 FEET)
  5. SMALL PAPER PLATE (ONE)
  6. ROCKS (1/2 LB)
  7. FROZEN CONTAINER W/ ICE

PROCEDURE:

FIRST, WE WRAPPED OUR CONTAINER IN A LAYER OF THE ALUMINUM FOIL. WE ALSO CREATED A LID FOR THE CONTAINER MADE OUT OF A LAYER OF RED FELT SNADWICHED BETWEEN TWO LAYERS OF ALUMINUM FOIL. NEXT, WE SECURED TWO OF THE STRAWS TOGETHER TO CREATE A CROSS HATCH OVER THE TOP TO MAKE A DOME SHAPE AFTER COVERING IT IN ALUMINUM FOIL. WE ALSO SURROUNDED THE CONTAINER WITH A 1/2 LB OF SMALL ROCKS. THIS WAS BECAUSE ROCKS DON'T HEAT UP UNLESS THEY'RE HEATED BY AN OUTSIDE SOURCE. WE USED A DOME SHAPE BECAUSE SINCE WARM AIR RISES AND COLD AIR SINKS, WE ASSUMED THAT WHEN THE WARM AIR RISES, IT WOULD COOL DOWN AND SINK BACK. WE DECIDED TO RECORD THE TEMPERATURE EVERY HOUR FOR 4 HOURS. OUR MEASUREMENTS WERE: -10°C, -5°C, -1°C, AND -1°C. WE ALSO LEFT OUR EXPERIMENT THERE OVERNIGHT TO SEE IF IT WOULD STAY COLD, BUT UNFORTUNARELY vAFTER BEING CHECKED AT 8:00AM ON MARCH 12, 2014, THE CONTAINER HAD MELTED AND HAD REACHED A TEMPERATURE OF NEARLY 20°C! THE COST TO MAKE THIS PROJECT WAS $9.75.
