What an incredible Entertainer! Keith called the day before to align on the event, he had made his research on the venue and its rules to be able to perform all his experiments safely and smoothly. He arrived early to prepare everything, before our guests arrived, which really ensured a stress free event and let us full mind to welcome our little guests. He entertained all kids (from 4 to 9 years old), and most of the parents, for more than an hour. We heard laughter, surprise screams, amazement gasps and shout of excitation during the all event. My daughter did not stop to speak about “the best party ever” the all week-end. It was a really special day thanks to Science boffins.
