Our Party Upgrades & Make-and-Take Options
SLIME
Ooey, gooey, there's nothing else on earth like it - it's SLIME. If you choose slime, we'll present you with an amazing chemical reaction resulting in this wondrous goop. Yes, it may be icky looking but our special chemicals are mess-free, child-safe and hassle-free.
SILLY PUTTY
You can tug it, mash it, roll it, and streeeeetch it. As with Slime, an intriguing discussion on the chemical reactions occurring during its production will take place. All the equipment will be provided and the children will be able to take it home. Don't worry, like all our experiments, this one is mess-free and safe.
SUPERBALLS
We don't just bounce them; we actually make them. You'll be fascinated by the process and amazed with the results - your very own Superball! The children will learn about the ball's properties and the physics behind the bounce. Note: this activity is only suitable for children ages 8 and up. It cannot be booked for parties with 24+ kids.

Happy Customers
Here's what parents have to say about our parties!
Professor Iggy was AAAMAZING!!! She was so pleasant and energetic. She was perfect in assisting the children that arrived late as well as those that needed assistance. The few adults that attended the party loved it. My daughter has requested her again for next year!!

The performer had excellent energy and was able to keep the kids engaged and interested for the entire hour. The performer was smiling Even during their experiments which showed that he was having fun and that was transferred onto the entire group of kids. It was a fantastic party overall and the kids thoroughly enjoyed it! Thank you!

I thought Karen did a great job of keeping a room of 5/6 year olds engaged and involved. They learnt something but had lots of fun too. I would definitely recommend a Mad Science Party. Thanks very much Karen!

FAQ
When and how do I pay?
Please have payment ready after the party is over. We accept cash or cheque (made out to Mad Science of Toronto). We also accept credit card payments over the phone and email transfers which can be arranged before your party.
+Do I need to provide anything?
We require a table so the Mad Scientist can setup the equipment. We do not require tables and chair for the children. The children ideally will be sitting on the floor in a semi-circle. We will also need access to water for set-up and clean-up and access to electricity. Please let us know if your party location does not have either of these.
+How far in advance do I need to book my party?
Our party schedule fills up quickly. We suggest you book well in advance to get the date and time you would like. Generally, at least 3 weeks in advance is recommended.
+What time will the Mad Scientist arrive? What time should the children arrive?
The Mad Scientist will arrive 15-20 mins before the start of the show to set up and prepare. We recommend you have the children arrive at least 15 minutes before the Mad Scientist is scheduled to perform, to ensure the presentation is able to begin on time.
+What kind of space do you require for the party?
An ideal party space is an open space for the children to sit on the floor preferably in a semi-circle. A room that can be darkened is preferred. The party is best performed indoors for the ultimate Mad Science experience; however, if this is not possible we can present outdoors during the late Spring & Summer months.
+What sort of mess are we looking at?
Parties are mess free! If you would like to place a tarp or sheet down on the floor for the children or the Mad Scientist, please do so before the party begins.
+What's your policy on tipping?
Please be aware that a gratuity is not expected. If, however, you feel the Mad Scientist has gone above and beyond your expectations please do not include the gratuity in the cheque.
+Are parents able to watch the presentation? Anything else we should know?
We encourage all parents and adults to watch the presentation. However, in order to facilitate the best experience we ask that any adults that are not interested in the presentation have an alternate space to socialize as to not distract from the show. Most importantly children and adults should be prepared to have fun!
