As our balloon carries the package above the clouds, the temperature will change quite a bit.  As you go up into the sky the air gets colder and our package will likely experience temperatures as cold as -50F! That is much colder than the temperature on the ground where even on the coldest day of winter we only get to close to -10F.

We need to make sure our package will have enough heat inside so the equipment will keep working when it gets really cold outside.

We will be using a Styrofoam box created right here in WNY by the design engineers at Armstrong Brands in West Seneca.  We chose Styrofoam for its light weight, ease of shaping and insulation. We will be adding some air activated hand warmers to provide some protection against the extreme cold.

Our student scientists found the base line temperature (coldest temperature reached under subfreezing conditions) to be at acceptable levels once multiple hand warmers are applied in close proximity to the equipment.

Some cool Styrofoam facts:

 Safe & Healthy Throughout Its Life Cycle

• Made of 98% air, EPS is an inert material without harmful chemicals that off-gas or leach during its use or disposal.

• EPS is widely recognized as a safe choice for use in food contact packaging by government regulatory agencies throughout the world.

Meets Performance & Cost Market Criteria

• Because of its versatility EPS offers significant savings in design and development, product assembly and distribution costs.

• With customized packaging designs EPS delivers exactly the right amount of product protection. Its high tensile strength and cellular structure give this lightweight product exceptional cushioning properties.

Maximizes Renewable or Recycled Source Materials

Recycled EPS is used in both closed-loop and open-loop processes to make a variety of applications from recycled-content foam packaging to durable goods and innovative new building products.

• In 2006 more than 52% of all EPS collected for recycling was used to make recycled-content packaging.

Uses Clean Production Technologies & Best Practices

Innovations in manufacturing technologies ensure EPS production minimizes energy consumption with mold cavities that cool quickly and manufacturing processes that recycle water and recapture air emissions.

Many EPS manufacturers are ISO certified.

Physically Designed to Optimize Energy & Materials

EPS feedstock is converted into a finished product 32 times its original volume-virtually turning air into a strong and efficient packaging material.

If all EPS packaging were replaced with corrugated cardboard, paper, wood, molded fiber etc., compared with current figures raw material requirements would rise to 560%, power consumption to 215% and the landfill volume to 150%.
