Great quality, it looks so gorgeous in my house!
Mystery Matter Box
Thank you for curating something so cool for the kids!!
The pin is high quality and I love that the ECG tracing is realistic not just a generic squiggle that sort of resembles an ECG.
I have yet to start a fire with this gizmo. I like to flash it around and get a reaction from certain people I know...I explain that if you have one of these at the ready you won't even need the tin foil on the windows to block those clandestine radio transmissions... This sucker will stop them cold!
So happy with the gifts- beautiful!
Everything came exactly as advertised.
Interesting element specimen in a cute tube! What’s not to love?
I was curious about my blood type so was naturally excited to find this and on sale. I have some experience with Rh testing so the process was familiar. The instructions were straightforward and everything was shipped well.
Pretty neat the kids really enjoyed them as well!
I gave my son a bath and handed him one of these. His amazement was worth the price. What's the practical effect though? It expands to a super-durable cloth about the thickness of two heavy paper towels together. I agree that this is a "couple-usage-then-dispose" item; but the real fun is the small form factor
My daughter and her chem teacher just loved this!
