BOBBING RAISINS
Bible Lesson:
  • Jesus gives us the Holy Spirit to us to be our helper. Isaiah 59:19 says “When the enemy comes in like a flood, The Spirit of the LORD will lift up a standard against him.” The Holy Spirit will lift us up and help us to overcome sin in our lives. We should be praying for the help of the Holy Spirit because Jesus promises He will give the Holy Spirit to those who ask for it. Luke 11:13.

Supplies:

  • A clear glass
  • A clear carbonated drink
  • 4-6 raisins
 
Directions:
  1. Pour the drink into a glass.
  2. Drop the raisins in.
  3. Observe the raisins.

Observe:
The raisins bob up and down because of the carbon dioxide gas bubbles in the drink. They are less dense, meaning their molecules are not as close together as the molecules in the raisins or in the drink.

Once the raisins start bobbing, they will continue to do so for about an hour.

The raisins will drop because they are denser than the carbonated drink.

Gas bubbles will attach to the wrinkles on the raisins.

When bubbles cover the raisins, they become less dense than the drink, so they will start to rise.

When the bubbles burst, the raisins again become more dense than the drink, so will start to sink.
