Observations
1.
Pour the baking soda BEFORE the vinegar
2.
The red dye and vinegar smelled like Easter
3.
As soon as the vinegar hit the baking soda it
bubbled right away!
4.
The bubbles/lava went up (erupted) about two
inches
5.
The eruption last about 15 seconds
6.
The eruption was successful but not as
successful as it could have been because the crater mouth of my volcano was too
big!
Experiment 2: Salt and Diet Soda
1 12 or 16 oz bottle of Diet Soda (why diet? Because when it
dries there won’t be a sugar residue on the volcano)
2 tables. Salt
Funnel
Place full bottle of soda in volcano crater. Pour salt into
funnel, using finger to plug hole. Place funnel over the bottle and release
salt. Stand back!

mountain
3.

The lava was brown instead of red
6.
Best eruption of the day because of the new,
bigger bottle!

Did you know that vinegar is also helpful when preparing poached eggs? Crack your eggs into a bowl [try not to break the yolks]. Add a pinch of salt to a pot of water and bring to a boil.
ReplyDeleteThen, before gently sliding the eggs into the boiling water, add a tablespoon of VINEGAR.
Why? The eggs will not spread out into the water; they will remain in tact. Cover the pot and wait 4 minutes [5 for firmer eggs] scoop eggs out with a slotted spoon.
Cut buttered toast into 4 triangles and place one egg in the center.
If you want to add a Fake Hollrndaise sauce,mix 1 cup of mayo with 1 cup of Ranch dressing; microwave on hi for 15 seconds.
