Can these experiments be repeated or is there only enough materials in the kit to do each experiment once?

There is more than enough matieral within the packets to get more than one go out of them. Multiple experiments pull from them, so they give a generous quantity, aside from the fact that a little bit goes a very long way. Something that is nice too, is that ordinary household ingredients are used for the experiments so that you can buy more if you need.

yes, there were enough materials and my niece has done many experiments. also, the materials are all natural and can be purchased at a grocery store, if you run out.

Yes, except if you buy the individual kit you can build all machines at once. If you buy the multi machine kit, you can only build one machine at a time as there are not enough pieces to build them all at the same time.

You can only build one at a time since most of the pieces are used in all of the featured designs but if u buy 6 ,and for this price it's not expensive, you can do all 6 at once. My brother did.

Yes you can but if you use it correctly you shouldn't have the need. For your safety, don't do it more than twice. If you still didn't get it all, wait 24 hours and try again. Hope this answers your question.

Hi, Amy, 'sorry for the delay in answering. I spoke with the teacher who managed the tie-dyeing with the children, who said she thought you would be able to use one kit. She based this on our use of the 3 oz. squirt bottles to help control the amounts per participant. We pre-loaded the little bottles (big ones come in the kit) so there was some of each color for each shirt, if wanted. Colors can be mixed, too, to make other colors. 2 kits might be better. I agree with lots of the answers you received. Some control over the amounts used will make the difference.

There were 2 tests for several different molds, but could only be used one time each. So you couldn't do any additional tests in additional locations.

Most often I have not been able to reuse them. There have been a couple of occasions that I have been able to use them twice.

I don't wholly recall, but I think each kit has a unique serial number; if for no other reason but to protect the integrity of the sample sent in for testing. You might want to ask the company directly to confirm.

There are seventy (70) experiments listed in the booklet included with the kit. The list of items that you need but are not included in the kit, is rather extensive, and includes about 33 items. Those items, helpfully, are listed on the front page of the booklet, along with a list of items included. There is also a "You Get It" list of ingredients under each experiment that calls for something that is not included in the kit. About 30 of them have such a list. Some of the items you need to get can probably be found around the average household. Some may require a shopping trip. I hope this helps you out. :) There are seventy (70) experiments listed in the booklet included with the kit.

Yes. The experiments use jumper wires to connect between components. When an experiment is completed or when moving to the next experiment the jumpers are removed. No soldering involved.

One time use, but for multiple tests. I bought 2 kits so I could test at my meter and after my osmosis.

I think there are 4 of each. We submitted 2 science projects using the items from this kit.

The kit contains ONE strip per test. So if you want to test 12 water sources you could pool them. A better plan might be to buy two kits and test a pool of 6 water sources for each. That way if one set is positive, you only need to buy 6 more, for a total of 8 kits, rather than 12.

I have this kit and its beautiful. I believe there is approximately 150 parts with many of them very small and very fragile. So be very careful when you are removing them from the sprues. Good luck and happy modeling

Yes you can. Just follow the instructions when you get the kit. It's very essy

Yes, each cartridge can only be once. The pack has 5 cartridges so that will give you 5 individual heating times.

There are kits that can be used several times but I believe this one is a one time use. I have not needed to use mine yet (knock on wood) but they do give a 100% guarentee. I bought this after my daughter dropped her Blackberry in the toilet for the 3rd time and after her ipone I wanted to be prepared.
