I should've read the reviews before purchasing. First, my box says Joyin (not Joyfy) so maybe what was sent to me is a knockoff and is why everything seems just like sugar and water. No crystal growing, Underwhelming everything. Not as advertised on the box. This item should not be sold.

Don't pick this one
We are unfortunately disappointed in this kit. We’ve tried several of the experiments now and none of them really work as described. The directions also don’t correlate to the correct sizes of supplies provided… for example it tells you to dump 30-50ml of water into a test tube but all the test tubes are only 15ml… so just not made very thoroughly or with any attention to detail. Would not recommend.

don't waste your time
the instructions have parts that are either missing or mislabeled. almost every experiment requires you to buy extra materials. the few basic experiments we were able to try didn't work in the slightest.

Perfect for toddlers (with close adult guidance)
My 4 year old LOVED this! Obviously requires an adult to read, redirect, etc. but super easy and my toddler was beaming and begging to do more.

Experiments don't work well
Many experiments have not worked. Chemicals don’t react properly. Crystals never grow. We have done about 20 experiments so far and only 3 of them have been worthwhile. Really disappointed.

Not working chemicals
Not working agents/chemicals that do not show any results. The experiment also requires you to bring a lot of stuff like white vinegar glue etc. also the balloon provided triggers a hazard to kids.

Scientist in the future? GET THIS!
Wonderful science kit with so many experiments to choose from. You can make it a weekend bonding moment or allow them to play independently (when it's appropriate). I bought this for my nephew, and he has an absolute blast being a pretend scientist.

Our kids have had a super time experimenting with this kit.
Our kids have had a super time experimenting with this kit. Almost daily they ask to do another experiment and are super interested in learning the why part of what's happening. And to be honest....it's have that as fun to help them do the experiments as adults!
