| | I was thinking of getting a large round bubble wand at Walmart and finding a bowl to match up to the diameter of the bubble wand; then I just need to stick the wand in a solution to get the film already on the wand and rest it on top of the bowl. This way I shouldn't have to play with the t-shirt and trying to stretch the solution across the bowl. I am going to try it tomorrow. Hopefully it will work. |

| The day I tried it, it worked great. When I did it for VBS it didn't work...so I did it again on the last night... still didn't work. The only thing I can think of is that my bubble solution was too strong. I don't know though. But even if it doesn't work, it still looks cool!

| | I did this experiment today. Hadn't had a chance to practice it before hand, as I am a little swamped directing, doing Sonic sing and Play, Bible Blast and Faith Fusion Finale (we are a small church and I just didn't have that many people who could cover the jobs). We found dry ice at a Publix grocery store, but not every one has it. I think we paid about 8 or 9 dollars for a 7 pound block. It was bigger than the bowl I was using so I broke it up and put it in. Still made plenty of steam. The only problem was I got soap solution in the bowl while practicing, so instead of the big bubble, I got tons, like when you blow bubbles in a milk carton. I was dissapointed that it didn't do what it was supposed to, but it still had a pretty cool effect, maybe even fit better the idea of bubbling over with thankfulness. And I got soap everywhere! But the kids loved it. And I tried it again after VBS without the soap in my water and it worked exactly right. |

| Hi,
The Kids were WoW when we did the experiment. At first it looked like it was not going to work as we got lots of bubbles but I kept going across the bowl with the soap rag and it finally put a bubble over the whole bowl and it just kept getting bigger and bigger as the kids yelled out things they were thankful for. At the end I said I was thank ful that the experiment worked as so many on the forum posted that they were having trouble with it. That got a laugh.

| | We ended up with the same issue with the soap in the bowl making the zillions of bubbles. The problem was that the bubble over the bowl kept breaking about halfway over, and all the retries got the soap in the bowl. I think there were more variables at play here, like the size of the bowl, what the soap solution should be - amount of soap vs. water, how soaked the cloth should be. Anyway, here in the city there isn't much call for dry ice, I guess, since I had to go across town to get it (20 minutes each way on an expressway), and paid a dollar a pound. The good part was, when the zillion bubbles came up, there were several
"oohs" to be heard, and many kids wanted to know, "where do you get that stuff?" So I think it made the point. Maybe that should have been the instructions - put the dry ice in the water and then add soap! |

| | Here's what I did, and it worked really well (and I am so grateful, since my first time was in front of all the kids!): I filled a large metal bowl about 2/3 full of very warm water. I added 5 lbs of dry ice, the smallest amount we could buy. You really only need about 2 lbs. On the table next to the large bowl, I had a long strip of t-shirt (as wide as the diameter of the bowl) soaking in some Dawn. The t-shirt was wet when I put it in the bowl, but other than that, there was only soap in the bowl. I picked up the shirt and ran it only around the rim of the dry ice bowl just to get a film of soap on it. Work quickly, because the soap freezes up very fast. Then I ran the t-shirt over the entire top of the bowl, rim to rim. You may need to do this more than once, so don't get flustered. As soon as you see a bubble forming in the wake of the rag, push the rag to the other rim and drop it on the table. In other words, it works best if you don't rub the rag back and forth over the top. Just work in one direction, repeating until you get a single big bubble. The kids were amazed into silence and had to be reminded to shout out the things they were thankful for. This isn't actually that messy. I had a tarp on the floor, but it just had a small puddle of water on it. The bowl did freeze to the table, but as soon as the dry ice had finished sublimating, the bowl came right off and it was easy to wipe the soapy solution off. Hope this helps someone--this was the experiment I was most nervous about and it worked really well! |
