Free Idea # 274 - Drinking straw with a detector strip

Invent a drinking straw with a detector strip down the side
that would indicate whether a drink contains any illegal
substances. Straws would be given out with drinks at bars,
pubs, and clubs to promote customer safety and highlight
the problem of drink spiking. If found positive the straw could
later be used as evidence, as some substances used to spike
drinks leave the body very quickly and can be difficult to
test for.

Free Idea # 273 - Vacuum cleaner with an integral carpet freshener function

Manufacture a vacuum cleaner with an integral carpet freshener
function. An adjustable switch or trigger on the handle would
dispense the user's preferred brand of carpet deodorizer through
a series of wide-spray nozzles on the front of the device. A dial
mechanism (similar to those used on steam irons) would allow
the user to adjust the intensity of each burst of the good stuff.

Create a pillow with a cooling patch inside so users can always
sleep on the cold side without needing to flip it over.

Free Idea # 271 - Pajamas with an in-built alarm

Invent sleeping suits (pajamas) with an in-built alarm that
would sound and vibrate, and would not turn off until the
wearer gets out of bed.
