Frey Scientific 130-7569 Bar Magnets Marked N and S, 2.75" Size (Pack of 2) Reviews

Used these for a knowledge machinate. Here was some uneveness to the magnetic fields and they werent as strong as I woudl have probable. But they did what we looked-for them to.

These magnets are barely passionate enough to hold to a vertical surface, like a refrigerator; they're not even close to the might of a rare earth pull (not that that's what I was in the family tree way, but still...).They have an impressed 'N' and 'S' on the two poles, which are easy enough to spot, and they are passionate enough to move some hard flakes almost on a piece of paper (like for a charm revelation). The metal also wears off a modest every time you soubriquet the magnets, meaning you'll have a affront spot on your fingers after land them (about the same as if you're land a lead #2 pencil).I just looked-for a austere bar pull for some difficult purposes, and this worked fine for me. For culture, these magnets are great (even if make sure you supervise kids with them!), but don't buy these if you're looking for passionate/flexible magnets.

Original out of the package neither magnet would stick to a vertical surface (solid steel anvil - plenty of ferrous metal for attraction). Similar poles (N - N, S-S) wouldn't repel including any force. Small fragments/splinters on magnets. Most terrible set of magnets I be inflicted including ever seen (and I've been buying magnets for projects and instruction for over 40 years). May be just a stroke of luck, but I wouldn't waste your time.

Frey Scientific 569885 PTC Taste Paper (12 Vials of 100 Strips) Shopper Reviews

Got these for one wits. To see if I were a supertaster.Not as good a superpower as it sounds. A bitter go meansyou are a bit more of a preview than habitual folk. Me and mywife tried them. I thought a bitter man with a bitter sled hammerattacked me. My wife tasted not anything.This amount of strips would be splendid for a instructor to pick up, good priceto entertain a total class for a bit. Good deal that. Me, I will be torturing for myself for being to come.

I've used these strips in my classroom for ages and they're always a hit. Plenty of strips in this to go almost, and they work impeccably!
