the first one we tried was using cold water and coloring it blue |
using card stock we were able to turn it over and with some careful effort |
Let go and see the pressure of the card holding up the water. We watched this done on a Bill Nye video on pressure and recreated in our home |
Next we tried another experiment from Bill Nye that didn't work out so great for us. we took a jar of hot water and color it red and then take a second jar of cold water and color it blue
We had a very hard time getting the jars to line up and the card stock would not slid out in one go which caused a problem with equalizing the pressure |
we colored two glasses of hot water red and filled two glasses with cold water. Notice the water is completely to the top of the glass |
Next we took two discs that were old and not being used |
and stacked them together covering the small hole |
and placed it on top of the hot water glass |
very slowly we slide the CDs together and watched |
while a small amount of red seeped thru the majority remained on top |
Hence seeing that the hot air (water in this case) is less dense than the cold water...this remained so until the two waters became the same tempture and then they mixed |
Take your toaster and use two cereal boxes to wrap around it |
cut out a slight hole so you can reach the levers in the toaster and set it at about medium temperature. The highest setting melted the plastic |
Next carefully placed a plastic bag over the cereal boxes and gently hold and turn on the toaster and watch as the bag fills with hot air |
Then let go and watch the bag rise up just like a hot air balloon:) |
take a tea bag that has a string and undo the string carefully |
unfold the teabag and empty out the tea |
Place the empty cylinder tea bag upright onto a plate and light it on fire |
watch carefully as it burns because as soon as it reaches the bottom |
It lifts off the plate, luckily it turns to ashes before it hits the ceiling:) |
