And lastly, an experiment designed at creating a lamp of the most state of the art variety. In fact, it is so practical that it does not require a bulb or an electrical connection. The components we will need are a glass bottle with a wide neck, sunflower oil, a glass of water, a plastic funnel, effervescent tablets, and food colouring. As the video reminds us, the more pills we use, the more bubbles that will appear in our wonderful lamp.
