Take advantage of Wednesday discounts for seniors 55+ while having some stellar fun at INFINITY Science Center. Senior Wednesday admission is only $9. Seniors also can get a jump on birthday and holiday shopping in the INFINITY Gift Shop with a Wednesday-only 5% off most items. They can take 10% off of lunch at INFINITY’s CaFe and even save $1 on a Possum Walk Tram Tour. Children 3 and under are always admitted free at INFINITY, so Senior Wednesday is also a great Grandparent Wednesday, too!
