A cafe for kids and their parents. Kids are issued with watersoluble spray paint and directed to the 'Wall' which runs down the middle of the cafe. They can graffiti away while parents sip a well earned latte. There are sub walls that can be rented and are covered with a roll of paper. The child can then take their grafitti home. The wall could be a rentable set up for kid's parties.
Ideas are everywhere. Sometimes all they need is a little dusting off, a little feeding up. Here are some for free. You can take any of the below ideas and develop them how you want. You don't have to pay me (though it won't be refused if you do) and you don't even have to acknowledge me. I suspect that if you have an idea you need to get it out there. Patents and other such stuff just clogs it all up. And if you sit on it too long then it blocks the ideas pipeline that connects way up there into the ether with the global ideas bank we all have access to- now and again.
Sword sticks are banned for some reason...but a hidden weapon is deeply attractive. The tickle stick (nod to Ken Dodd here) is a legal variant of the sword stick. A fancy walking cane, which with a press of the hidden release button reveals a long rubber prong with a feathers at the end for tickling someone about to attack you. Might work some of the time...
You're out walking in your stylish but oh so short goretex/paramo/super waterproof jacket and it begins to bucket down. But you aren't wearing over trousers. The rain slides down the coat and drenches your thighs and backside, your wallet gets wet and altogether it's pretty miserable. But with the belt skirt all is reversed. A simple nylon belt that contains a packed away 'skirt' of sil-nylon. This is unvelcroed and allowed to hang down with a toggled elastic to tighten around the legs if required. The rain runs down the coat and hits the skirt and misses the legs entirely.
When I travel for a single night or two I like to travel light- only a shirt and a toothbrush needed. But I don't want to carry a tube of the stuff in my laptop case. Nor a wet toothbriush. Enter the toothtube- a cunning easily washed item into which you place your tootbrush; it includes a sealable section at one end which you fill before laving with a couple of squirts of toothpaste. You can pop it into your jacket pocket and go!
Wii tennis is OK but a tad dull. Real tennis (wikipedia it) is like a weird cross between cricket and fives and tennis. Deeply English and played indoors in a special court. Trouble is these courts are few and far between. Wii real tennis brings the Royal game of Tennis to your front room...
As a boy I loved meccano and its wooden predecessor, bilofix. What about hulking great 2x4s predrilled with convenient holes, predrilled flat panels, long bolts with wing nuts- all made out of wood and delivered to your home to make massive structures fast such as instant sheds, treehouses, workshops, car ports or sculptures, follies, climbing frames etc? Great for father son bonding. Easily torn down the following weekend.
