So I wrote a review the other day and promised to update it after an event my daughter attended. Unilocal has removed it, I don’t know why. I love Mad Science, or I should say, my kids love it. My 8 yr old son has gone to the«lab» for a few things and had fun and learned a bit. My 3 year old just did her first Mad Science workshop. It was called Mini Mad Scientists. I don’t know how, but the entertained and controlled 15 kids under the age of 5 for 3 hours. I got my grocery shopping done and she learned lots. Definitely worth it.
