Need an empty bottle for science?

Photo Sharing and Video Hosting at PhotobucketOne of the experiments in Physical Science requires the use of an empty 2 liter bottle.  The only time we purchase a 2 liter bottle of soda is when someone in this household has a tummy ache, and we purchase Sprite.  For the experiment we wanted to do;  we needed a clear bottle.  So, what to do?  I have some rules about soda.

  1. Try not to drink it. Ok, I fail at this one.
  2. Never buy 2 liter cokes, because I will drink it.
  3. Never buy 2 liter cokes for anyone else, because they will drink it and I’ll drink it.
  4. Never buy 2 liter cokes and dump out the coke because it is a waste and I’d drink it.

So, what to do?

Answer:  Buy diet coke and do a science experiment without wasting the coke.  😀

Step one:  The partners in crime.

Sept two:  Get brainy husband to make a thingie for the top of the bottle.  We need to be able to drop the Mento into the bottle from a distance.  The brainy husband makes a tube with a slot in it.  Then we have a trap door with a string attached.  Can you see it?

Step three:  Drop Mento in the tube and let it rest on the trap door.

Step four:  Use string to pull trap door and watch the show.

Step five:  Be disappointed because the there wasn’t a high velocity of diet coke and it didn’t cover the neighbor’s house.  😦

Step six:  Have no fear.  Brainy neighbor and brainy husband are brain storming of ways to make it better.

Step seven:  Now clean out the bottle and use it for Module 5 in Physical Science

  1. You need a narrower and longer tube for the geyser effect; which are now available for the low cost of $19.99. ::jaw drop::

    Two science experiments in one—you did well!! 😀

  2. My kids love doing this experiment. The mentos that come in a tube roll work really well. I even bought a pack of mentos that had a plastic tube around it to use just for this fun project. The kids are chomping at the bit to use it.

    I think that that you are going to have to buy more soda. 🙂

  3. Yep, you’ve got a good brainy husband there 😆

    Just FYI, I held the cursor over the Physical Science link at the bottom of your post and I got the Snap Shot of your post on the Nativity banner that you made for Christmas.

  4. Thanks, Elaine. I don’t get a snap shot, but it does go to the right link.

    Sheri, the brainy husband and neighbor have already decided what was needed and will use what is in our garage at a low cost of nothing. LOL $19.99 that’s stupid.

  6. Drat on the non-high velocity spatter….tragic!

  7. Michelle, that is way better than pouring it down the sink. Brilliant!!! 😀

    That’s not a big spew though.. I got bigger by shaking a 2 liter vigorously until the lid popped off. I was a teen at the time and well, some teens do stuff like that. I was inside at the time, there is no telling how high it would have spewed had the ceiling not been in the way.

  8. Oh and I almost forgot to say, it is always nice to see pictures of the things you and the brainy man are up to.

  9. ROTFL Donna that is great. I’ll get two bottles next time and get one of the kids to shake it…outside. Did you have to clean the ceiling? Talking about high velocity, I was working at a fast food place and I decided to jump on the corner of a ketchup package. I think there is more ketchup in there, than anyone really thinks. Yeah, teens do stuff like that.

  11. That’s funny Michelle! It’s probably good for the world we weren’t in the same town as teens.

    I didn’t have to clean it. Mom and Jim (stepdad) did. They didn’t fuss at me and they were smiling. I was glad to have such gracious and understanding parents. 😉

  12. Too funny! When I need 2L of soda, I just take a couple to class and tell the students their first “assignment” is todrink the bottle dry! It makes me the “favorite” teacher. That’s very important, you know.

    Oh, I do the same thing for the lab that requires cans of soda. I tell them all to bring one from home, but then I bring cans w/ me too and they “have” to drink one before class starts. Should be interesting this year since my class is 1st period.
