Design Prototypes by Betsy Stretch https://padlet.com/betsystretch/dfyd2mpxbdob39c9 Made with a lightning strike of genius en-us 2021-06-10 17:48:07 UTC 2025-04-22 13:00:56 UTC hello@padlet.com Group 6 - The ice cube sits in the center of this structure. It is surrounded by a layer of bubble wrap ($10). Four sheets of foil are layered on the walls outside of the bubble wrap ($16). For a floor, we used foam ($40). We then used a cut craft stick ($20) to create a structure that can support "Space Umbrellas" which has foil (4x$4) create a reflective surface removed from the actual ice cube structure. https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610383484 The cost is $102]]> 2021-06-16 16:33:46 UTC https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610383484 Group 4 https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610384227 2021-06-16 16:34:11 UTC https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610384227 Group 5 katherinedosland https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610388463 We chose to use aluminum foil and aluminum foil cups because of its ability to reflect light and because of its ability to minimize heat transfer. We chose to use bubble wrap because the air in it acts as an insulator. We use the cotton balls as well for their insulating properties. ]]> 2021-06-16 16:36:20 UTC https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610388463 Group 7 heather_cohen https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610389256 2021-06-16 16:36:42 UTC https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610389256 Group 7 explanation heather_cohen https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610391042 2021-06-16 16:37:31 UTC https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610391042 Group 2 https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610394745 2021-06-16 16:39:15 UTC https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610394745 Group 3 https://padlet.com/betsystretch/dfyd2mpxbdob39c9/wish/1610402020 The mylar outer tent and foil bottom will reduce radiation from the heat lamps.
The multiple layers of foil and paper will also reduce radiation transfer as well as conduction from the bottom of the box and the convection from the air that will heat up inside the tent.
