Could I make a similar contraption for my bottle? This would give me a device that I could replicate a designed shape over a series of plastic bottles




Familiarity - High tech/low tech: individuals are likely to be more familiar with low tech objects instead of high tech ones. For example, many people will know all the features of a plastic bottle - the cap, the thread, the bottle and the label, whereas the same people are unlikely to know all the components of a printer (see post dating back towards the beginning of the year)
Music shaker/percussion - quite a simple idea, but one that is also very quick to create: put some rice in the dry, empty bottle and away you go!
Timer - a little more complex, playing around with the hourglass concept. The bottle would have to be cut/drilled for this to be achieved. Is this a way forward?
Bird feeder - a bit like blue peter? but valid all the same, again would require the bottle to be altered physically.
foot roller/massager - fill up with warm water and use the designed grip and surfaces of the bottle to massage your feet
fruit juicer/squeezer - again, using the designed shape of the bottle for a different purpose. The ridges on some bottles make a perfect surface with which to rub a halved fruit against. The juice naturally runs down the side of the bottle in to the container waiting below.
