Techstravaganza is committed to offering all students an equal opportunity to participate in the outreach event.

If you are part of a STEM organization, we would love it if you or your representatives could come to host a display or demonstration at Techstrav! Sponsors and exhibitors will receive exclusive benefits, including the chance to network with bright high school students and display their logo on our flyers and t-shirts. Please contact us at if you would like to learn more.


Question: Can I still attend the event even if the tickets are sold out?

Answer: Yes! The tickets on Eventbrite are free and serve as an estimate for us to plan the event. Registrations may also be used to send updates about the event such as parking at the event. Please join us on the 21st regardless of whether or not you are able to reserve a ticket!

Question: Is this a school-sponsored event?

Answer: Yes, Techstrav is hosted by Thomas Jefferson High School for Science and Technology, a STEM magnet school in Alexandria, VA. The event is completely student-run, organized by a club called Tomorrow's Women in Science and Technology (TWIST), and funded with the support of local organizations.

Question: Are there ID or minimum age requirements to enter the event?

Answer: None! The event is open to students of all ages and their families and friends.

Question: I am the parent of a child. Do I need to register a ticket for myself?

Answer: If you will be viewing the demonstrations with your child, please register a separate ticket - if not, feel free to only register one for your child. This registration is meant to help us estimate how many viewers will be participating, depending on how you want to participate, please register the appropriate amount of tickets.
