There's a lot of this around my way at the moment - a few weeks of very wet followed by a heat wave has got them moving. They crop up usually on alder or pines near water. I've never spotted a…Continue

So this failed in a neat way - feeding physarum on 1% fluorescein. Turns our slimes own pigments are such strong uv absorbers that the dye doesn't get a look in. But, where the slime's started to…Continue

Slime mould food choices

"The agar is just made up with water - no nutrients. I let the agar set then put paper on top and spray it. You could try setting paper into the agar, it might make a more stable substrate. I don't have problems with mould over 7 days but I also…"

Slime mould food choices

"p.s.  I'm wanting my timelapses to be about 5-7 days long. Agar in a pitri dish does well, same with agar in a plastic container, but paper always dries out fast, often gets moldy quicker too. "

Hello! Thank you for the warm welcome! I’m excited to get working with some slime mould. Just spent the day hunting/photographing some in Epping forest but pretty sure I got 95% mushrooms. Any chance I could send you some pictures of what I think are slime mould spore capsules for your opinion?

Oh that would be amazing. I was looking at ordering it from the US. Is there any issue with getting it through customs?

Hi Ian, thank you for wanting to send the Physarum, I was just wondering if you could tell me when they will arrive, it'll help a lot with our planning :)

Raising from Spores - Zero Tech Method

Posted on April 11, 2017 at 13:30 0 Comments

I've been looking for a way to rear physarum from spores without resorting to bacterial lawns and needing autoclaves etc.

I've only done a couple of trials but this method seems to work ok, it does require a bit of patience.

I used petri dishes and filter paper but any container and a bit of tissue should work.

The idea is to let the food go off producing bacteria for the amoebal phase to feed off then slowly dry them out so they get persuaded to form…


Big bang, big disappointment :)

Four weeks of crazy work,  turning the spare room into a culture lab and time lapse studio I made enough culture for two thousand people and I should be there with my friends and colleagues on the stand inspiring the next generation of scientists,  slime fans and eccentrics.  

Unfortunately I'm stuck on a hospital ward with fifty stitches in my neck waiting until I'm allowed home. So it goes I suppose but damn I was looking forward to the Big Bang Fair,  I couldn't even bring a slime…


Plotting and planning....

Getting involved with several schools in my area running STEM club activities - I'm trying to design a six week course on our dear sticky friend that'll be adaptable to ages 12-17. Looks like it'll be fun ( and a lot of work ). My own cultures have been dormant for a while aside from raising the odd batch but I should start playing again soon. 

Raising slime again..

Blimey it's been a while, we've got the finals lab projects for the students at work on at the moment so I'm not getting time to play. I've got a session with 95 school kids booked in in June so I'm raising as much slime as I can cope with in preparation for that. 

I'm planning on getting them to make Plasticine mazes in petri dishes for their cultures so they've something to take home.

I've also got these intriguing mycena cholorophos spores ( a glowing mushroom ),…
