Wildly Successful: A solar-powered model of the Queen who makes tiny lightbulb-unscrewing waves. Her handbag is what harnesses the solar power. You can also get the limited edition Diamond Jubilee model, if you want to make a spectacle of yourself. Get both! Make tiny weapons, pretend Past Queen is here to kill Present Queen! Don't forget the optional solar-corgi.
Less Successful: Marmite Gold
