  1. Quicksand Project Anna Wendt Lauren Stanberry Mr. Spangler Whitefish High School Advanced chemistry

  2. Quicksand… in a Bucket!!! What role does density play in Quicksand? The finer the sand we use, the better quicksand.

  3. Background Information • Quicksand is ordinary sand but saturated. • Reduced friction • Movements cause you to sink • Solid ground that is liquefied by water • If the water can’t escape from the sand, it becomes liquified • The “quick” refers to how easily the sand moves around under the weight of an object

  4. More Background Information • Flowing underground water • Upward water makes sand more buoyant • Earthquakes • Shaking ground increases pressure of groundwater

  5. How did we make this so called Quicksand???? Put a hole in the side of our awesome green bucket Then put a bunch of little holes in the bottom of our blue bucket. Put the blanket on the top of the green bucket Slid the blue bucket in the green bucket with the blanket very snug Hooked up a hose Sand in the bucket

  6. First Experiment • Fine Sand • Water coming through the bottom of the bucket, going up • Draining the water and testing to see if it worked

  7. First Experiment with Alex

  8. What happened to Alex? • Her foot was able to get out of the “quicksand” fairly easy, no difficulties OMG I almost fell over!

  9. Lauren, what are you doing? My hand is still in the bucket! There’s too much Water!!! We decided to change our experiment a bit After we tried to figure out what we were even doing.

  10. We Added Salt After trying out 1st Experiment! We Made a new Experiment!!! After doing research, we found out that most quicksand is located where there is saltwater. So we added ½ pound of salt to our 5 gallon bucket of water and sand.  It’s so cold!

  11. This is our Amazing Video Lauren’s foot in a bucket!!! This concluded the awesomeness of salt in the quicksand. Saltwater definitely makes a difference. 

  12. Data and Stuff Sample Tested 13,779 g = .91 g/mL 15,141.6 mL Concentration of Salt Test 2: .50 lbs of Salt : 4 Gallons of water 773.91 g = 1.19 g/mL 650 mL Concentration of Salt Test 1: .25 lbs of Salt : 4 Gallons of water

  13. Conclusion • The finer the sand, the better the quicksand. • Having water come up instead of pouring it on top of the sand works better. • Salt water works better than normal water. • Because our density was only .91 g/mL, we did not actually make quicksand.

  14. Improvements • Tried different types of sand • Tried creating an “earthquake” • Tried to make a giant pool of quicksand for everyone to try out and enjoy
