Looking for the ultimate Valentine's Day gift? Why not a stunning, colour-changing rose that will captivate her senses? This amazing creation is based on XYZWorkshop's "Colour Changing Rose" from Thingiverse (http://www.thingiverse.com/thing:152642), with a thrilling twist - simply touch the two wires at the stem end to activate the LED and alter its vibrant hue. **Gift Instructions** You'll need these components: * 5mm LED * 2 x A13 1.4v Batteries * BCX38C transistor * Single-core telephone cable * 3mm O/D Drinks straw (for rose stem) To assemble your colour-changing rose, follow these easy steps: Drill a 5mm hole in the centre of the rose to accommodate the LED. Attach the batteries and LED to their respective holders. You may need to bend the LED's legs slightly to ensure they fit properly. Label the positive and negative ends of the LED for easy identification. Slide a single-core wire between the battery terminals, allowing you to connect it to the transistor and LED. Solder the positive wire from the batteries to both the LED's positive leg and a length of single-core wire that will slide down the stem.
