  2. We will always strive to offer you the nearest available Boffin but the acceptance of your booking fee does not guarantee availability.

  3. You will be given in advance the name and mobile phone number of the Boffin(s) attending your party. If you have any concerns on the day, do not hesitate to call the Boffin if the office is closed. Boffins must keep to a time schedule and appreciate your guests being ready at the appointed time.

  4. You are requested not to provide food or drink during the presentation and to encourage the children not to wander off to any other attractions that may be present.

  7. All parties are quoted based on a continuous presentation. We do not have any stops between sections apart from perhaps a short comfort break which can be prearranged.

  8. Please be aware that there is an inherent risk with Pop-Corn that some of the kernels will not pop and this presents a hazard to teeth. Please ensure your guests are aware of this as we cannot be responsible for any injuries.

  9. The party organizer must inform us of any known allergies before the party.

  10. We will always do our best to ensure that dry ice is delivered in time but we are dependent on third parties over whom we have no control and therefore we cannot guarantee or be financially responsible for late or non-deliveries.

  11. All adults are most welcome to sit in on the presentation, but a minimum of one adult always present, please. If there are several adults, we do request that they respect the presenter and remain quiet.

  13. We operate a Money Back Guarantee. We hope this will never happen, but if you are unhappy with the Presentation or the Presenter stop the Boffin within 30 minutes of the start. Tell him/her that you are dissatisfied and the reason for it. We will refund in full whatever you have paid us for the Presentation as well as any costs paid to us for mileage.

In your slime pack you have:

  • 100ml bottle of Polymvinyl Alcohol 
  • 25ml bottle of sodium Tetrabroate 
  • 5ml Slime Colouring 
  • 5 pots
  • 5 lids 
  • 5 stirring sticks 


How to make Slime

1. Pour approximately 20ml of polyvinyl alcohol into your pot. This should be enough to cover the bottom of the pot.

2. Add 10 drops off your slime colouring to the polyvinyl alcohol and stir with your stirring stick 

3. Add 50 drops (5ml) of sodium tetraborate to your solution and stir 

4. If your slime is still quite runny add 5 drops of sodium tetraborate at a time until it goes slimy. Remember to keep stirring too; good slime takes time!

5. When you're not playing with your slime, remember to keep the lid on it so that it doesn't dry out
