Suggestions where to take 2.5 year old for some indoor fun?
I, by the grace of god, am off from work tomorrow … on a weekday during the school year. I would like to take my son out somewhere he can have a little fun after being stuck in the house all winter. Any suggestions where I can bring a 2.5 year old?

What Travellers Say
Reviews Summary
Visitors often praise the Long Island Explorium for its engaging, hands-on STEAM exhibits that spark creativity in children. The beloved sand boat and communication stations are consistent hits. However, some find the space smaller than anticipated and occasionally note missing supplies in craft areas.
"We love the Long Island Explorium! It may look small from the outside, but don’t let that fool you—there’s so much to explore inside, especially if your child is into STEAM.
My boys always find something new to dive into, whether it’s building, experimenting, or just getting hands-on with science.
My oldest even had a birthday party here a while back, and it was such a hit with the kids. The staff is great, and the space is packed with interactive fun that sparks creativity and curiosity.
It’s one of those local gems that makes learning exciting—and it’s right by the water, which makes for a perfect family day out!
By the way we got our tickets through our local library."

"Super disappointing. Incredibly small, ill equipped. No paper or working markers at the arts/crafts corner. Just literal trash. The rice boat was out of order. The activities that were available consisted of ‘stack sugar cubes’ and a table with those magnetic shapes everyone has at home. Save your money."
Rachel
"My daughter and I visited on Saturday and it wasn’t crowded. You can buy tickets but I had a pass from the library. My first impression was not great as I expected the two story building to have note to explore, but only one floor was accessible. However, my 4 year old loved the signal area where they could send messages. There was a crafts area with all the necessary supplies like glue and tape, and books available. My daughter also had her first VR experience and there was a green screen for taking photos with fun backgrounds. You can send those pics to your own phones for free. Overall, it was okay, but don’t expect the extensive exhibits you might find in children’s museum; 1-2 hours will be more than enough to do all the activities."
