Are you able to redo these experiments or can you only make each one once? I am wondering if I could use this with my science class, thanks

you can do them as many times as you want... you can do one and undo it, then do another one and undo it... you can even mix them in one circuit ... :D ... I bought ScienceWiz / Electricity Kit too.. and my sons (5 & 7 YO like to mix them all.... although these two kits have very similar stuff it's fun and my kids don't need to fight for material .... I warn you, these are very simple material that any one can get anywhere, but this kit is cute for a kid :)

Yes, my 7 yr old & 5 yr old did the experiments together. As long as someone can read the instructions.

Cristina, I haven't tried this. If you're near a medical library (larger hospital or medical school), one of the librarians may be able to help you. They may have tried this or read about it. And another thought, write to the company. Let me know what you find out. Charles

Hi, I used this at an event before and made about 10-15 consecutively. Then there was a long wait before I had to use it again. Just be prepared to refill the ice after you make each one. I was preparing myself for the burning smell when an appliance is run for too long but it didn't happen.

Found this response on the Leap Frog web site. May help answer multiple questions. http://leapfrog.custhelp.com/app/answers/detail/a_id/2173/session/L3RpbWUvMTM1Mzg5NTM5MS9zaWQvSWRVVWVjY2w%3D

I just used the picture. That worked for me. However if you can't go by the diagram just do what looks good. When you start laying the crystals out it starts to make more sense where they go. Number of arms and cups verses the crystals. Just have fun....

I guess with the huge variety they come with I never asked myself that question. If you look on the net, there is a pdf file of complete instructions for this unit. You can read it or download and print it. There are SO many things this unit will do that I actually printed a copy. (and have used it several times) Wish I could be more exact. Good Luck.

I'm not sure if you can do this. However, what's the reason or advantage you envisage by doing this ??. I suggest you go straight with 2xD cells. It will be simple with amazing results.

I did. :) I bought it for that exact reason. My students loved it. We mixed it with putty instead of slime, but it would probably work with slime, too.

Hi. I'll be honest, I gave this to all the girls in my class and wouldn't let them open it at school because of the parts...I didn't want them lost. I really don't know. Sorry I couldn't be more help.

I couldn't tell you one by one- but I can tell you a round about. A lot of them involve boiling and cool down time and ofcourse, mixing. Approximately half hour or so for each to get them started. The longest part is waiting for them to grow.....days. One of mine took two weeks to show anything remotely close to a stone. And some of them have another step you take after the stone has grown a little, like gluing it on a string and hanging it into the solution so you can watch it further grow longer. Do not expect "big" results. These are tiny- like pencil eraser tiny. I even tried doubling up on the experiments---still small crystals. It is neat though. I think I was more interested than my 6 year old though in watching them grow. Also- if you do hang them on string- don't use regular glue. Invest in a glue gun or they will fall off from the moisture. And....I suggest gloves when using the blue/purple powder. I had to use bleach to get it off my hands.

Technically, yes. There aren't enough cups and test tubes for each of them to do some of the investigations so they would have to share. I think there are plenty of chemicals to do the investigations more than once, but most of them are probably things you have in your kitchen anyway or can easily purchase (baking soda, vegetable oil, citric acid). This kit does require a lot of adult supervision. You won't be able to just turn them loose with it.

a couple of years ago I volunteered in an Outreach science workshop for middle school girls and I used them for an intro to spectroscopy at an elementary level. we passed the glasses out and while the girls played around with them marveling at the rainbows in the lights we explained refraction and spectrums, it was a lot of fun and i think the children got a kick out of the glasses. i don't believe you can use them for 3d tv's their pretty much just for filling your world with rainbows.

That's what we did. We usually stacked them in groups of 3. We took them out briefly one stack at a time to examine & photograph then put them back in the incubator in a different order. From what I could tell neither the stacking nor the time out of the incubator impacted the experiment. All of our samples continued to show growth each day.

Actually, Joseph, I've wondered that same question but have been reluctant to try it. I only used one cartridge and wasn't real impressed with the outcome. Let me know if you find out the answer to your question. Peace to you, Janie

I ordered one of these and received it in 5 days(Obviously my results have no bearing on your results) however rereading your question????, it makes no sense, you should be clear in your question if you want a clear answer.

Please let me know what you think of it once you've tried it out. (It's encouraging to hear Tony used it.) Also, I'd like to know what equipment I need to use in conjunction- I don't have my own smartboard in my classroom and I'm not sure if I can borrow one long-term! But if I can just hook it up to my computer and project it on a screen, I think I'm good to go! -I look forward to hearing from you!
