SCIENCE | Harry Potter: the Exhibition
I'm not sure how scientific this exhibition about everyone's favourite boy wizard is. In fact, you'd think that a movie that tells kids brooms can fly and serpents turn people into stone might offend the eggheads at the Ontario Science Centre, but apparently not. They're so excited about the exhibit that tonight the OSC is keeping its doors open til midnight on Friday and Saturday to accommodate all the city's Potterites who are expected to show up in droves, eager to immerse themselves in JK Rowling's fantasy world. Visitors will have the chance to try on the Hogwart's Sorting Hat, pull a mandrake from its pot, and even play Quidditch (or at least a simplified, non-aerial version of it). The show also has on display over 200 of the props used in the movie, including Harry's wand and trademark glasses. Runs til May August 22.
Ontario Science Centre, 770 Don Mills Road, $20 - $27, Friday and Saturday 10 am - 12 am, regular hours 10 am - 6 pm

GALLERY | No Sleep
This show at College St.'s Industtrees Gallery boils visual art down to its basic units: a pen and a piece of paper. The work of seven artists who specialize in ink drawings and share an obsession for meticulous detail will be gracing the walls at the tiny gallery (one of blogTO's faves by the way), including emerging young talents Filip Anton, Andrew Remington Bailey, Reid James Jenkins, Peter Kalyniuk, Alexandra Mackenzie, Laruen Pelc McArthur, and Joseph Thomson. Each artist participating in No Sleep has chosen their own way to depict otherness with figures and faces that have been distorted and twisted; some are silly, some are unsettling, and some are even disturbing enough to make you lose sleep over (hence the show's title). The show launches with a opening reception tonight and runs until May 7.
Industtrees Gallery, 1234 College St., Reception 8 pm - 11 pm, Gallery hours Wednesday to Saturday 12 pm - 6 pm

PARTY | BikeSauce Fundraiser
In this city, bicycles and activism are as inseparable as the wheel and the road . BikeSauce is the latest bike shop to open in Toronto, serving the Queen East community as not only a place to keep your ride in tip top shape but also a hub of cycle advocacy. Run by volunteers, BikeSauce offers DIY repair services, providing access to tools, parts, and knowledge and empowering riders with the ability to fix their own bikes. It's also a social space to meet with like-minded cyclists and discuss ways to make Toronto more bike-friendly. Tonight the shop holds a fundraiser at Blue Moon, featuring hot indie rockers Hooded Fang and the hilariously-named Abdominal and the Obliques, as well as locals Entire Cities and Bike Jazz.
Blue Moon, 725 Queen St. East, $5 - $10, 9 pm

PARTY | White Girl
The Radar's pick for your Friday night party fix is White Girl at 751. Queen St.'s double-deckered dive bar will be packed with the titular caucasian females and their admirers, imbibing cheap booze and dancing the night away to the best hip hop to hit the scene since the early 1990s. Manning the decks are DJs Patrick Macguire and Scott Pilgrim (yes, actual name), whose current claim to fame is his recent nude sprint across the intersection at Yonge and Dundas. Assuming he's taking requests tonight, here's mine: keep your clothes on, Scotty!
751, 751 Queen St. West, Free, 10 pm

GALLERY | Art for AIDS
Although often overshadowed by acute emergencies like the Haitian earthquake or the Asian tsunami, HIV/AIDS remains the biggest health crisis of our time. The epicentre of the crisis is Sub-Saharan Africa where a staggering 22.4 million people are afflicted with the disease. Because of the chronic nature of the disease and the risk of donor fatigue, those fighting HIV face a constant struggle to raise awareness of the problem. Raising awareness is the goal of Art for AIDS International, the organizaiton presenting an exhibition of works by 25 artists from around the world at the Gladstone Hotel this week. Artists from Europe, North America, Asia, Latin America, and Africa have contributed to the event, alongside students from Canada, South Africa, Uganda, Mozambique and the Netherlands. The art has been on display since April 5, but tonight's launch party is a chance to mingle with event organizers and learn more about the project. All the art is on sale, with proceeds going to benefit grassroots projects supporting women and children in Sub-Saharan Africa.
Gladstone Hotel, 1214 Queen St. West, Free, 7 pm

MUSEUM | ROMkids Sleepover
Inspired by the famous sleepovers at New York's Metropolitan Museum of Art, the ROM is giving kids their very own night at the museum tonight. Youngsters will have an unforgettable night sleeping amongst the exhibits and will be treated to a wide range of activities, including afterhours access to the new Schad Gallery of Biodiversity and the newly renovated Bat Cave (cause nothing gives kids a good night's sleep like making them walk through a dark, bat-infested tunnel red before bedtime). They'll also get a chance to talk with the museum's experts, touch specimens, watch movies, and sing some karaoke. Take your kids to this and you'll be in their good books at least til Christmas.
Royal Ontario Museum, 100 Queens Park, $75 adult and child, 5 pm - 10 am
