Cornstarch Monsters - Non-Newtonian shear-thickening fluid in a speaker cone

[ohheycrystalhey]

How exactly did you create the soundbox? Do you need it for this particular experiment? I'm trying to do this for a school project but I'm not sure how.

@ohheycrystalhey Hi, I used 15mm thick MDF board and PVA wood glue + nails. I cut the wood on a band saw and used simple butt-joins. It is just a simple empty box with optimal internal volume for bass resonance (the volume was given in the instruction manual). For the top part I used a jigsaw to cut the round hole for the speaker to sit in and then screwed the speaker into it. This part was screwed and silicone-sealed on to the box in case I ever needed to get inside.

@ohheycrystalhey The sound box is not absolutely necessary, although you get FAR louder sound! What is necessary is some way of holding the speaker still otherwise it will shake itself off the table! Also, this particular speaker has a plastic cone with butyl rubber lips and is sealed, so there is no need to cover it with anything. I see some commenters are worried about this - the speaker is still working just as new, just wipe it dry after the experiment.
