sticky Review by jessica

Not a bad kit for the price and makes LOTS of slime but it is sticky, sticks to your hands... (Posted on 3/9/13)

Exciting Review by Norina Geter

The students truly enjoyed this experiment,especially since they have enough left over to do at home with family members.
However, there needs to be included a [larger] mixing cup to mix the two chemicals together because when stirring ,it spills out and the experiment isn't enjoyed or successful.
Also, perhaps have science kits with different colors vs. just 'green'. (Posted on 2/25/13)
