Scientific lab report

Have you ever wondered What would happen to oil, water and food colouring if the Alka-seltzer tablet hit it? First we watched a video about what would happen when we did the experiment. Mr Morell got eight cups and filled four of them up with oil and he other four up with water. Miss gloag layed down paper towels on the mat and then placed the cups of oil on them. Next Mr morell poured the water in the cup with the oil.Then the teachers dropped 5 drops of food colouring in each cup. We waited for a bight and then we dropped the Alka-seltzer tablets in and it made a cool concealed explosion. Finally the teachers asked four students to tip the liquid out into the sink.  Once the water hit the vegetable oil the water went straight to the bottom. Next when the food colouring hit the vegetable oil it slowly made its way to the water. Then when the alka-seltzer tablet tablet went in it made cool concealed explosions that looked like waves. As soon as the alka-seltzer tablet hit the surface of the water it started making red ear bubbles come up out of the water into the oil. The bubbles started getting bigger until eventually it looked like a volcano explosion inside of a cup. After that the explosions started getting smaller but as I figured out at home they started again if you put more water in the cup.The first one, which was the one miss gloag was doing, the food colouring was blue and it took awhile for it to reach the water. The blue one also didn’t have an as big explosion, probably because the alka-seltzer tablet took longer to get to the bottom. The second one was the green one and one obvious thing about that one is that it had more drops of food colouring in than the others. The green one's alka-seltzer tablet went to the ground quicker than the others which meant the explosion was bigger. Next it was the black one which had way more oil in the the others which the there was more oom for the explosion so the explosion was bigger. Also the black one obviously had less water which made the explosion not go for as long. The final one was the red one but I didn’t get to see so I don’t know what it did. Our result was really cool, it was pretty much a homemade lava lamp except it was at school. What happened was the water had food colouring in so we the alka-seltzer tablet entered the water a made a wave like explosion, the funny thing is that it was concealed. The explosion started off small but it started getting more wave like. Once it got big I felt like the water was going to come right out of the cup. Eventually the explosion died down and four people went and tipped out the contents. One thing that I learnt was that water and oil do not like each other and they separate almost instantly. When the water hit the oil it started making ear bubbles and that was because the water and oil didn’t like each other. Something else that I learnt was that food colouring was pretty much 100% water. When the food colouring hit the oil it slowly started making its way to the water because it’s made of water so it doesn’t like oil. As soon as the alka-seltzer tablet hit the oil it slowly made its way down the bottom to the water. As soon as the alka-seltzer tablet hit the water it started to disintegrate.
