Water Experience
A few days ago we did a lab involving water. We had to do three experiments. The first one was called Pennies. What we had to do was me and my partner had to count how many drops of water can fit on a penny. We had to use water first to see how many drops and then alcohol. Me and my partner each were in the 50s, but with the alcohol it was different it dropped in the 20s. In our next experiment we used wax paper and drops of water. Our task was we had to put a drop of water on the wax paper and try and cut the drop with a tooth pick. What happened to the drop was the drop stood a circle. The drop moves with the toothpick as it goes right threw it. our last experiment is called stringing you along. We used 2 beakers one empty and one filled with water and 1 piece of string. Me and my partner held one end of the string. The challenge was to pour water into the string and have water run down the string and collect water into the empty beaker. The solution to the challenge is the longer the string is and angle it will work. The water sticks to the string and flows down it.
