Colour-changing light bulb

iLC Colour Changing Light Bulb

It’s easy to give your home a fresh feel with one simple colour-changing light bulb, and this one comes with a lot of different functions. You can switch between 12 colours and four modes: fade, smooth, flash and strobe. The remote control also lets you adjust the brightness of the light and set timers to turn the bulb on and off automatically.

Fisher space pen

Fisher Space Pen Cap-O-Matic Ballpoint Pen Matt Black

Pens with hidden capabilities might be the ultimate gadgets – they're a staple in classic spy movies, after all. This one doesn’t shoot bullets or tranquilliser darts, but it does have the ability to write in extreme conditions.

With its gas pressurised cartridge, it can continue working on almost any surface and at any angle – even upside down. You can use it underwater and it’ll also cut through greasy surfaces without trouble. Plus, it’ll continue writing at any temperature between -34°C and 121°C.

Famously, the space pen can even work outside of the Earth’s atmosphere. But if you don’t get the chance to put it to the test, you can still benefit from its long-lasting ink cartridges. They hold out for three times longer than the average pen.
