Our task was to send a single pringle back to us via the Royal mail post. We used a cardboard box, some cotton wool and a sandwich bag. We put the sandwich bag and the cotton wool into the cardboard box and celloptaped it shut. We then put it in an envelope, stuck a fragile sticker onit and sent it away.
When it got back, we opened it up and unfortunately it was crushed to pieces. Our objective was to send the pringle and it to come back in one piece. If we were going to change our design we would put more packaging in the box so the pringle couldn’t move.

My group’s pringle survived in perfect condition. First we put it in a box with cotton wool and we put the lid on then we put it in the envelope with some bubble wrap and some fluffy bits.
After it had been through the post we checked it and it was still in perfect condition. I think that it did not break as it was not under too much pressure from the wool. The wool had a big surface area so it was less likely to break.
Our pringle experiment………..
Our pringle experiment was to invent and make a brand new safe and sturdy packaging for a single pringle to stay in one piece for the planned journey to mail from the school and back.
First, we designed a strong box to ensure that the pringle would stay in one piece.
After that we started to pick out specific and convenient pieces of scrap materials to build/make the packaging. Such as; cardboard, sellotape, polystyrene to ensure the safety on the edges of the box for the pringle.
Soon after that, we placed the pringle into the box and cautisously put the cotton wool into the box, covering and surrounding the pringle to ensure extra safety. All of these materials which we used to create the box made a lot of endurance to help the pringle stay in one piece.
Once the package returned, we discovered that the pringle stayed completely intact. We think that even though the force in Newtons was great, we needed the polystyrene to keep the cotton wool in place and psread rhe force over a larger surface area. This will reduce the pressure and hopefully protect against impact.
