Science Boffins were amazing from start to finish from booking to the performance. We were kept updated leading up to the party. Option to purchase party bags through them and on Amazon. I’d set aside an evening to put all party bags together and when I opened the box was very surprised to see these had already been put together. The actual party was amazing and Boffin Dave kept all children aged 5-7 engaged and amused for the full 90mins. Somethings do go wrong with experiments and the children found this hilarious - especially when the lemonade bottle exploded all over science Dave. Highly recommend.
