Came undamaged with a pair of gloves and a syringe. ### ⭐⭐⭐⭐⭐ Amazingly cool but messy, heed the warnings *by on Reviewed in the United Kingdom 12 October 2022* First of all, nobody is kidding about the mess. Don't think "oh, I'll just be careful" because this stuff has a mind of its own and I spilled it just opening the lid to pour it. But there is a warning in the leaflet, and so I was well equipped with gloves, foil tray, jar with a lid, newspaper and kitchen towels etc.And it is a lot of fun to play with! You'll need pretty strong magnets, though - school-grade buy-in-bulk red and blue iron magnets didn't do the cool spiky thing you see in photos and videos. Buy neodymium magnets if you want to see the spikes. ### ⭐⭐⭐⭐ Brilliant for magnetism practicals *by on Reviewed in the United Kingdom 30 March 2022* Worked really well but had to decant into safer bottles as the bottles they came in leaked ## Frequently Bought Together - first4magnets?
