For the last few days our class was doing science in the science lab.... Alot of science. Were learning how make make something called bubbles in a bottle. Basically it is like a lava lamp but it has many bubbles. We used test tubes instead. We had theses things to do it:
(1) A test tube.
(2) 1/3 cup of water.
(3) Food colouring (Red works best for me!)
(4) Oil.
(5) Fizzy tablet.
All we did is we added the water about 4 CM high, then added oil to just below the top. Then we added food colouring. The food colouring touched the top of the water. Then it went into the water. Then we added the fizzy tablet. When the tablet went into the water little bubbles start coming then a whole lot of them. The food colouring gave the bubbles gave its colour. I saw something surrounding the bubbles. It look like spikes kind of thing. It was really the fizzy. It went well. Very well.:-)
