I have used Science Boffins a number of times and this has always been great. Boffin Harry is great with doing experiments including dry ice and slime making. This is always popular with the families. Service with Science Boffins is also great and easy to book. Overall a fab company with excellent service. Would highly reccommend. UPDATE - I can't thank Science Boffins enough I had a Boffin booked in for a Halloween Party, however, the Boffin that was due to come was unwell. The Office managed to find a replacement at short notice and the party could still go ahead. Great Service and a Big Thanks to Annette in the Office for sorting this out.
