Today we had a science expo and we all had to show a science experiment.
Callum M and Tom did mentos in a bottle to found the difference between diet cola and cola, the diet cola was the best because it went the highest.
Holly and Keeley did fake blood, it looked like a lava lamp but it was just food gel and oil.
Macleod and Lewis made a hovercraft, they stuck a bottle top on a CD and a balloon on the bottle top then blew it up and it hovered on the table.
It happens by the air flowing out evenly under the CD and makes it hover.
James and Lachlan's experiment was about penny cleaning. They put white vinegar and salt together, stirred it, then put the penny in for ten seconds and it cleans the penny but it must be copper.
Lucy and Isla their experiment was called avoiding pepper. You need pepper water, a dish, dish washing liquid, you put the liquid on your finger with water and pepper in the dish then put your finger in the middle of the dish and the pepper flies to the side. It happens by the liquid breaking down the stuff in the pepper to move to the side.
Next was me and Blake, we did coloured water. You put a match in blue tak, stick it in the middle of a dish, pour in some water, light the match, then put a cup over the match and the water will rise up the cup.
Aidan and Morgan did tornado in a bottle, it was two bottles on top of each other with water in them with tape around them. When you twirl it around and watch the tornado.
