Just following up from my original post asking for ideas for slime party, We found Slime Planet who were absolutely fantastic, the party was yesterday and Chris from Slime Planet came in and ran a great slime workshop. He managed to keep 10 5/6 year olds entertained for an hour, making lots of slime plenty of which they could take home. They made a giant slime at the end which created much excitement. And the best thing Chris takes away all the messy bits at the end so clearing up is pretty pain free. Would highly recommend them for parties and they also run various Events too. https://www.slimeplanet.co.uk
